Yes. Most GNU packages do exactly that. The FSF actually maintains a
special mini library for this very purpose: a collection of stand-ins
or replacements for missing or unusable functions in the system
libc. It's called 'libiberty', for the fun of linking it by the gcc
option '-liberty'.

You'll find 'libiberty', or parts of it, in many GNU packages, as a
subdirectory. If you program is going to be GPLed, I think you can use
libiberty in it, and avoid implementing your own.
