Thanks Kris & Wojciech for replies.
Its great to get it confirmed that FreeBSD Libc is only /usr/src/lib/libc/* as I presumed.
I have compiled and installed the FreeBSD Libc into a temp directory. The size of /tmp/libc.so.7 is about 65,000 bytes smaller than /lib/libc.so.7.
The /lib/libc.so.7 is dated May 25, 2008. I did not touch CFLAGS or anything other than DESTDIR. But I really forgot, the gcc version is different. The /lib/libc.so.7 is by gcc 4.2.1, but the /tmp/libc.so.7 is by gcc 4.3.0. May be the code generation of the latest gcc may be better.
I think the size difference may not be an issue as the libc is get it compiled and installed without any error.
The GNU glibc has a "make check", but there is no make check target for FreeBSD libc. How do you guys test it? Is the /usr/src/tools/regression/ any help for that?
