GCC-4.0.0 (C++) is very broken on cygwin.
Have a look at test results, here:

http://gcc.gnu.org/ml/gcc-testresults/2004-12/msg00544.html

There is a problem with pthreads and the recently added weak-linkage
support for windows targets.

But I'm glad to see someone is keen enough to test the bleeding edge.
Care to submit a bug report?
