RE: glibc problems

It seems the below can be fixed simply by removing the "extern int errno;"
and placing a "#include <errno.h>" at the top of the file.

I just wonder if "errno" is not guaranteed to be an int then the places in
Moto that have "switch(errno)" will surely not work and may need to be
rewritten to not depend on an int.

There are not that many places in Moto that use errno luckily.

Here is what I get when trying to compile Moto on Red Hat 9:

cd tmp; ar -x /root/moto_0_19_1/lib/libcodex.a
