And also remember not to use getwd, which is deprecated, and have your static
glibc handy if you intend to use stat/lstat and the family - if you fail to
include the ld.so ld script which pulls libc.a in, then something like this:

if(foobar)
xstat = stat;
else
xstat = lstat;
will not work, gcc screaming about undefined symbols. lstat and the rest
are weak in shared glibc and are defined only in libc.a.
Also lchown always returns failure (use chown), getopt doesn't want to
keep order of the arguments (even if you set up the environment as described
in docs) - the old trick with optind doesn't work, you have to pass '+'
as the first character of short options to get the REQUIRE_ORDER behavior.

I have just recompiled my entire system to use glibc (2.0.30, based on
Slackware 3.1, but nothing has left from this dist ;-) and had no special
problems using it. The only thing using libc5 is Netscape now ;-)

The patches are not that huge - and they are almost always the same!
