Hi Nick,

Thanks for taking the time to look at this.

I've only seen the problem on Open Solaris (2009.06 - x86), and only
after updating to 2.20. A range of 32 and 64bit FreeBSD, Linux, and
OSX systems all work fine.

Yes, it's in pthread.h, apologies they were already being found on my
system. pthread.h is patched to define PTW32_STATIC_LIB. I've attached
the three files - version.rc, pthreads.h and winver.h (from w32api).

It's the first time I've used it, but here is the log from gdb:

The program no longer exists.

Ok, I'll give that a try. Specifying the default 0 via the -c option
also segfaults, so it seems this should work.

Thanks,

Tony
