I've attached hte following for review since I took the liberty of
replacing two #if __GNUC__ >= constructs in regex_internal.h with
__GNUC_PREREQ calls.
2005-09-15 Derek Price <[EMAIL PROTECTED]>
* regcomp.c, regexec.c, regex_internal.c: Back out previous
changes, consolidating in...
* regex_internal.h: ...this file. Replace two #if __GNUC__ >= X
with calls to...
(__GNUC_PREREQ): ...this new macro.

I wasn't completely sure what you meant, thought you might still be
trying to elicit comment from others, and wanted a quick fix for my
immediate problem. I think I understand what features.h does in a glibc
context, but I'm unsure how that would fit into this pure/always_inline
issue, much less GNULIB.
Regards,
Derek
