I guess I like doing things manually. But thanks for the patch. Anyway, 
(note also that cluts.c should now return correct nr. of failed tests, 
that would've been a valid critique)

Strange, SUSv4 (which is really the std I'm testing for compliance 
against) says it should be there. I'm surprised you don't have any 
issues with SUS-specific functions. So, do you want me to replace limits 
with param.h?

Ah, wherever I do this, I think the path isn't big anyway (cluts.c and 
buf.c). I'll keep it in mind if there's ever a chance they might be. Agreed?

Thanks, I didn't even know about that one!

I already have my sreturnf function for such purposes (right now it uses 
vsnprintf). Why do you think *snprintf and *asprintf aren't portable?
