ExtUtils::MM_Cygwin - methods to override UN*X behaviour in ExtUtils::MakeMaker
=head1 SYNOPSIS
use ExtUtils::MM_Cygwin; # Done internally by ExtUtils::MakeMaker if needed
=head1 DESCRIPTION
See ExtUtils::MM_Unix for a documentation of the methods provided there.

=item maybe_command
Determine whether a file is native to Cygwin by checking whether it
resides inside the Cygwin installation (using Windows paths). If so,
use C<ExtUtils::MM_Unix> to determine if it may be a command.
Otherwise use the tests from C<ExtUtils::MM_Win32>.

}
=item dynamic_lib
Use the default to produce the *.dll's.
But for new archdir dll's use the same rebase address if the old exists.
