regex_internal.h modification lead to GCC crash

[Yoann Vandoorselaere]

Hi list,

Recently introduced modification to regex_internal.h lead to a crash
when compiling GnuLib regex module under FreeBSD-4.11 GCC-2.95.4. 

The same module is reported to compile successfully under FreeBSD-5.4,
GCC-3.4.2.
The GCC crash was traced down to the following addition:

+#if !__GNUC_PREREQ (3, 1)
+# define always_inline
+#endif

Commenting out the '# define always_inline' line fix the problem. 

Compilation log from the user who reported the problem (who is in copy
of this mail, and might be able to provide more information upon
request):

<oge> In file included from regex.c:57:

Hope it help,
