So don't expect, for example, uClibc# compiled with Linux kernel 2.0.x to implement lchown properly, since 2.0.x# can't do that. Similarly, if you compile uClibc vs Linux 2.4.x kernel headers,# but then run on Linux 2.0.x, lchown will be compiled into uClibc, but won't# work at all.

You must also generate# a locale file for anything but the C locale. See directory extra/locale for# a utility to do so.

This # can be lots faster and safer IMHO.## "malloc-930716" is from libc-5.3.12 and was/is the standard gnu malloc.# It is actually smaller than "malloc", at least on i386.
