I've attached MT-SAFE versions of dirname() and basename() derived from

that dirname() and basename() in FreeBSD's libc aren't weak symbols. I
presume that NetBSD's libc has the same misfeature.
$ nm /usr/lib/libc.so|grep basename

0004fca8 W basename
$ uname -sr
NetBSD 5.1_STABLE
At least NetBSD knows how to build system libs.
But I do not know how to hijack a weak symbol.
Simply by having a non-weak symbol present, the non-weak symbol will be
used for resolving instead of the weak symbol.
