Have you considered using ACE?  It is an excellent toolkit _and_ it is 
part of the main Debian distribution, hence it is DFSG-free!  It
provides a standard thread interface across, POSIX threads, UNIX
International and Win32 threads, and much much more.  ACE is the
Adaptive Communications Environment, a C++ toolikit/framework.  It 
even provides a standard interface for socket programming across UNIX and Win32.  It really is a great
library.  Check out the description of the "libace4.6" set packages in 
dselect for good synopsis of what ACE can do.

I happen to be in the research group that develops ACE so please excuse 
my "advertising." :)
