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

See ExtUtils::MM_Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.

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.

}

=item B<init_others>

Override some of the Unix specific commands with portable
ExtUtils::Command ones.

Also provide defaults for LD and AR in case the %Config values aren't
set.

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

Adjustments are made for Borland's quirks needing -L to come first.

Changes how to run the linker.

The rest is duplicate code from MM_Unix.  Should move the linker code
to its own method.

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