Wrong level of abstraction, not portable.

I don't use Windows but would never call something not available on
Windows portable.

You miss:
   - add some defines,
   - check the compiler support this correctly (try once exceptions with
     gcc 2.95 and threads for one thing for which you need compiler support)
     and add the corresponding compiler options
   - check all libraries you use are thread save, included OS libraries and
     language libraries, and that protecting by mutex the one which are not
     is enough.

Well, stronger than you think (look up the threads on c.l.c++.m where one
speak on threads).
