Seems like it is:

$ rpm -q glibc-devel
glibc-devel-2.5-24

$ rpm -ql  glibc-devel
...
/usr/lib/libm.a
/usr/lib/libm.so
/usr/lib/libmcheck.a
...

zlib seems to be installed also:

$ rpm -ql zlib-devel
/usr/include/zconf.h
/usr/include/zlib.h
/usr/include/zutil.h
/usr/lib/libz.a
/usr/lib/libz.so
/usr/share/doc/zlib-devel-1.2.3
