This choice may also be dictated by the equipment available to 
developers. I'm running three OpenMP-capable machines (Opteron, HT P4, 
dual P3), all running Linux (although the dual P3 could run anything, I 
guess, being a scratch machine.)

I have no idea of anyone is interested in OpenMP under Cygwin or MingW 
on Windows.

From a practical standpoint, pthreads would seem to be the most 
universal option. I should also take a look at how the Boost thread 
libraries handle this.

Perhaps we can create a configuration model akin to the current 
--enable-threads setting, perhaps choosing an implementation based on 
that setting. Of course, that requires more work... but support for 
inclusion in GCC mainline is important, I think.

I live in Florida; we vote, but judges make the final decisions. ;)
