You want want to take a look at www.ysl.org. (I'm the principle
maintainer so I'm a bit biased, but others who have used the YSL's think
they are not too bad either).
Basically the YSL's are a growing set of C++ class libraries. In there
are C++ wrappers for threads and semphores. All classes work fine under
both win32 and linux. you will need a very recent egcs to handle the
some of the template classes, but if nothing else you can get some ideas
on doing the thread stuff in C++ by looking at the code.
