Forgot to add, I did some testing to see if similar problems aren't
elsewhere:
#!/bin/sh
for i in `rpm -ql glibc-headers`; do perl /usr/src/libc/scripts/begin-end-check.pl $i; done 2>&1 | grep -v OK
for i in `rpm -ql glibc-headers`; do
cat > /tmp/a.c <<EOF
#include <features.h>
#undef __BEGIN_DECLS
#undef __END_DECLS
#undef __BEGIN_NAMESPACE_STD
#undef __END_NAMESPACE_STD
#undef __BEGIN_NAMESPACE_C99
#undef __END_NAMESPACE_C99
#include <$i>
EOF
gcc -E /tmp/a.c -o /tmp/a.i > /dev/null 2>&1 || continue;
for flags in "" -D_GNU_SOURCE -D_ISOC99_SOURCE -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_SVID_SOURCE -D_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -D_XOPEN_SOURCE=500 -D_XOPEN_SOURCE=600 -D_BSD_SOURCE -ansi -D_POSIX_SOURCE -D_POSIX_C_SOURCE -D_POSIX_C_SOURCE=2 -D_POSIX_C_SOURCE=199309L -D_POSIX_C_SOURCE=199506L -D_POSIX_C_SOURCE=200112L; do
gcc $flags -E /tmp/a.c -o /tmp/a.i > /dev/null 2>&1;
perl /usr/src/libc/scripts/begin-end-check.pl /tmp/a.i | grep -v OK | sed "s~^~$i $flags: ~"
done
done

and math.h (plus tgmath.h that includes math.h) were the only 2 reported
headers.
