Re: Join not linking in threads (Compile error)

[Federico Montesino Pouzols]

        Yes, this is a known bug in 1.0.8, join is not linked in on
win32 (not only mingw) systems since it is inside an #ifdef
WIN32. This is fixed in CVS for 1.0.9, which should be released soon,
as soon as we process some pending issues. You can fix it by moving
the definition of join outside the #ifdef WIN32 (in src/thread.cpp),
for instance right above the definition of
ThreadImpl::ThreadSigSuspend.

        As for `#define HAVE_OLD_IOSTREAM', it is needed for Mingw
systems based on gcc 2.9x, but as you have noticed, gcc 3.x does not
like it.
