To be clean.
Concerning the static variables, I didn't put any variable
declaration/definition in the header, only macros.

The patch is attached.

It could be an option, but there's no way to pass it around like it's done with
recursive and resume, because it's used all the time (just see how many time you
pass resume or recursive in function calls).
Furthermore, I declared it as static, so it won't be exported by the linker,
contrarily to many other global variables (username, password, dots, etc). At
least, put all these variables static.

Because in every single function/system call I know (except inet_aton) returns 0
on success, non-zero otherwise. Hey, you're the onse talking about consistency!

cheers,
