PATCH: build problem with signals on HP/UX,ia64

I traced the cause of the signals problem on HP/UX (ia64). The cause
was the preprocessor output as opposed to awk. The relevant lines of
sigtmp.out look like this:

#line 3

with all subsequent signals also indented by one space. signames2.awk's
regex looks like this:
  /^XXNAMES XXSIG[A-Z][A-Z0-9]*[\t ][\t ]*[1-9][0-9]*/ {

Obvious fix would be to add ` ?' to the beginning but the patch below adds
`[\t ]*' because I'm supposing that some other preprocessor might someday
decide to use some other indentation. I'll hold off till tomorrow before
committing this.

Current status with respect to HP testdrive machines is as follows:

Tru64 4.1               - couldn't log on so untried
Tru64 5.1   ev7     cc  - builds and tests fine
Tru64 5.1   ev7     gcc - untried (gcc was a broken symlink)
HP/UX 11.11 PA-RISC cc  - builds fine, completion tests using zpty hang,
                          otherwise fine
HP/UX 11.11 PA-RISC gcc - builds fine, tests fine except zpty fails to load
HP/UX 11.22 Itanium gcc - builds fine, tests fine[*], zpty fails to load
HP/UX 11.22 Itanium cc  - signals problem above, with the fix, all is okay:
                          build fine and and test okay (except Y01 zpty hang).
I was trying HP/UX 11.23 yesterday with similar results to 11.22. Haven't
tried it today. Haven't tried their BSD machines either.

Compilers on the Itanium systems seem to be quite different from those

Since zpty failing is far from critical, that really just leaves AIX to
worry about. Unless we want to clear up the compiler warnings too.


[*] actually a test in A04 fails because rm -f * didn't get rid of all
the files (it is not a local filesystem and rm fails a bit). I also get
[[ -g ... ]] tests failing on all HP testdrive systems because you
can't set setgid on files. Would it perhaps be worth doing tests with
files in /tmp or /var/tmp if we find it to be writable. That'd remove a
lot of NFS related failures.
