=head1 NAME

ExtUtils::MM_NW5 - methods to override UN*X behaviour in ExtUtils::MakeMaker

=head1 SYNOPSIS

 use ExtUtils::MM_NW5; # 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.
