Re: gcc for building Perl on WinXP

It would really simplify things for win32 PDL if an easy,
1-click addition for gfortran were available.  We're spending
a lot of development time working around the lack of a
fortran compiler on win32 perls.  Since gcc includes one,
it is more of a packaging and distribution issue than one
of existence.

Cheers,
Chris
