package ExtUtils::MM_Win32;
=head1 NAME
ExtUtils::MM_Win32 - methods to override UN*X behaviour in ExtUtils::MakeMaker
=head1 SYNOPSIS
use ExtUtils::MM_Win32; # Done internally by ExtUtils::MakeMaker if needed
=head1 DESCRIPTION
See ExtUtils::MM_Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.
