That's right. Gcc's runtime libraries and headers have a
runtime-exception, which explicit allows redistribution. But
pthread-library doesn't come with such an exception, so I strongly
recomment not to bundle it hardly with gcc and its runtime-libraries.
IMHO it would be best to implement in gcc the threading API by using
native win32 API for our targets. The other chance - but here a
volunteer is required - is to implement the posix-thread API as
PD/BFD/ZPL/MIT/etc and make it part of our runtimes. So we would have
the same behavior by this as cygwin is doing.
