Re: gcc for building Perl on WinXP
dmake test passed all except the known problem with t/pthreadBarf.t. Also, I think we can fix the breakage in pthread.h by doing the undef in our pdlmagic file that is including pthread.h.

Hi kmx- The detection for the pthread library is currently broken. To build PDL with pthreads you'll need to explicitly set the values of WITH_POSIX_THREADS, POSIX_THREADS_INC, and POSIX_THREADS_LIBS where the comment indicate what worked for my strawberry perl install was: WITH_POSIX_THREADS => undef, POSIX_THREADS_LIBS => '-LC:/chm/strawberry/pthreads/lib -lpthreadGC2', POSIX_THREADS_INC => '-IC:/chm/strawberry/pthreads/include', and the C:/chm/strawberry/pthreads contained the pthreads install location.
