=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.

    return '' if $self->{SKIPHASH}{'dynamic'};
    $self->xs_dlsyms_iterator(\%attribs);

=item xs_dlsyms_ext

On Win32, is C<.def>.

Changes the path separator with .

=cut

=item B<maybe_command>

Since Windows has nothing as simple as an executable bit, we check the
file extension.

The PATHEXT env variable will be used to get a list of extensions that
might indicate a command, otherwise .com, .exe, .bat and .cmd will be
used by default.

=cut

Using \ for Windows, except for "gmake" where it is /.

Override the default link and compile tools.

LDLOADLIBS's default is changed to $Config{libs}.

=item cd

dmake can handle Unix style cd'ing but nmake (at least 1.5) cannot.  It
