regex workaround for gcc 2.95.3 core dump

I installed the following to work around a build failure of coreutils
CVS on OpenBSD 3.4.  (For now I have resisted the temptation to enable
__attribute__ only for GCC 4.0 and later.  :-)

        * regex_internal.h (__attribute): Define to nothing for GCC 2.
        This works around a core dump on OpenBSD 3.4, which has GCC
        2.95.3, which dumps core when given __attribute__(()).
