Subj : creating library to be used in threaded and nonthreaded apps

I'm writing a shared library that is designed to be reentrant.  (No 
static data, etc.)  It is safe to call from multiple threads simultaneously.

I'd like to make one version of the shared library that I can use in 
both threaded an nonthreaded applications, without forcing the 
nonthreaded apps to link against the pthreads library.

I *think* I need to do at least something to tell the compiler how to 
deal with stuff like errno, but maybe that's implementation-dependent?

Is this possible to do in a portable way?  If not, is it possible to do 
on Linux with glibc/NPTL?

Thanks,

Chris
