Fixes errors

regcomp.c: In function 'parse_bracket_exp':
regcomp.c:2724: error: invalid storage class for function 'seek_collating_symbol_entry'
regcomp.c:2757: error: invalid storage class for function 'lookup_collation_sequence_value'

make[2]: *** [/home/dank/queue/jobdir.fast/crosstool-dev/build/x86_64-unknown-linux-gnu/gcc-4.0-20050305-glibc-2.3.3/build-glibc/posix/regex.o] Error 1

See also http://sources.redhat.com/ml/glibc-cvs/2004-q3/msg01071.html
That fix requires gcc-4.0, but the fix proposed here works with older compilers, too
