With the following aczshoot.m4 function (included from acinclude.m4)

AC_CHECK_HEADERS(stdarg.h varargs.h termios.h termio.h)


AC_DEFINE([ZSH_OOT_MODULE], [], [Out-of-tree module])

and the following patch, the complete config.h is unnecessary.  The uuid
module doesn't need stdarg.h, varargs.h, termios.h, termio.h, or
RETSIGTYPE, however.  Any thoughts?
