Tried again on AIX 5.2 after compiling up gawk. Seem to have gotten further,
and seems to have a sane sigcount.h file. The error seems to be similar to
those highlighted here (http://www.zsh.org/mla/users/2002/msg00247.html),
however, removing "cap" from config.modules, and running 'make prep' then
'make' didn't seem to do the trick.

/usr/vac/bin/cc: 1501-216 command option -version is not recognized - passed to ld
C for AIX Compiler, Version 6

Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .c suffix: C source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .o suffix: object file for ld command
4. file name with .s suffix: assembler source file
5. file name with .so suffix: shared object file

Options:
Options can be flag options or keyword options:

1. Flag options:

-# Display language processing commands but do
not invoke them; output goes to stdout.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-brtl Tells the linkage editor to accept both .so and .a
library file types.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.
-L<dir> Search in directory <dir> for files specified by -l<key>.
-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p Generate profiling support code. Same as -qprofile=p.
-pg Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q<x>, -qinline<x>
Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
a = assembler
b = compiler backend
c = compiler frontend
i = compiler inliner
I = inter-procedural analysis - compile phase
l = linkage editor
L = inter-procedural analysis - link phase.
p = preprocessor
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlc; output goes to stdout.
-V Displays commands as they are invoked by xlC;
output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<a,b,c,f,I,l,L,p>
-y<x> Specify compile-time rounding of constant floating-point
expressions, where <x> can be one of the following:
m = round toward minus infinity
n = round to nearest
p = round toward positive infinity
z = round toward zero.

2. Keyword options:

Keyword options are specified in one of the following ways:

-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>

where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.

Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlc command.

Options without parameters:

32 Selects 32-bit compiler mode.
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.
cpluscmt Permit "//" to introduce a comment that lasts
until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).
dbxextra Generate symbol table information for unreferenced
variables. By default such information is not generated
thus reducing the size of the executable compiled with
the "-g" option. Same as -qsymtab=unref.
digraph Allow special digraph
dollar Allow '$' as an identifier character
dpcl Generates symbols for tools based on the Dynamic
Probe Class Library (DPCL)
extchk Perform external name type-checking and function
call checking.
fdpr Collect information about programs for use with
the AIX fdpr (Feedback Directed Program Restructuring)
performance-tuning utility.
flttrap Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.
fullpath Specifies the path information stored for files when
you use "-g" and the symbolic debugger.
funcsect Place instructions for each function in a separate csect.
heapdebug Enables debug versions of memory management functions.
hot Determines whether or not to perform high-order
transformations on loops during optimization.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst
with the -Idirectory option. If -qidirfirst option
is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
largepage Take advantage of 16M pages, which will allow for
reduced TLB entries and allow hardware prefetching
to be done more efficiently.
ldbl128 Increase long double size from 64 to 128 bits.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.
listopt Display the settings of all options; output goes
to .lst file.
longdouble Increase long double size from 64 to 128 bits.
longlit Changes implicit type selection for integer constants in
64-bit mode.
longlong Allow long long integers.
macpstr Allow '\p' as the first character of a string constant
which will be replaced by the length in bytes.
makedep Creates an output file that contains targets suitable for
inclusion in a description file for the AIX make command.
mbcs String literals and comments can contain DBCS
characters (same as dbcs option).
mkshrobj Create a shared object from generated object files.
noprint Direct listing to /dev/null.
nostdinc Specify which files are included with the #include
"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
report Adds information to the listing file on the loop
transformations that have been carried out.
This option requires either -qhot or -qsmp
in order to have effect.
ro Put string literals in read only area.
roconst Put constant values in read only area.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.
smallstack Reduce the size of the stack frame, allowing better use
of a limited stack size.
source Produce a source listing; output goes to .lst file.
srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggressive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
threaded Indicates to the compiler that the program will execute
in multi-threaded environment.
tocmerge Read from the file specified in -bImportfile linker
option and merge the address information to access
ranges of external addresses using a single Table Of
Content entry.
upconv Preserves the unsigned specification when performing
integral promotions.
warn64 Enables checking for possible long-to-integer or
pointer-to-integer truncation.
unwind Enables stack unwinding. The optimization prologue
tailoring reduces the number of saves and restores
of non-volatile registers, but is enabled only when
stack unwinding is disabled.
xcall Generate code to static routines within a compilation
unit as if they were external routines.
xref Produce a cross-reference listing containing
only referenced names.

this option if the run-time rounding mode
is round toward minus infinity, round toward
positive infinity, or not known.

arraypad - The compiler will pad any arrays where it
infers there may be a benefit. Make sure
that you have not used equivalence
association for any arrays in files
compiled with this option as the compiler
does not perform any checking before
padding arrays.
