Re: gcc for building Perl on WinXP

I got it to work with the following:

Add after the POSIX Threads comment block in pthread.h:

> #ifdef PTHREAD_CREATE_JOINABLE
> #undef  PTHREAD_CREATE_JOINABLE
> #endif

in order to remedy the fact that perl has added a macro
with the same value.  If the pthread one is not already
defined then the perl one is---but this breaks the w32
pthreads include file.

Then set the parameters in perldl.conf to

> WITH_POSIX_THREADS => 1,
>
> POSIX_THREADS_INC  => undef,  # '-I/usr/pthread/include'
> POSIX_THREADS_LIBS => '-lpthread',  # '-L/usr/pthread -lpthreadGC2'

It is building away as I type.  Will let you know how
dmake test comes out....
