=head1 NAME

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 L<ExtUtils::MM_Unix> for a documentation of the methods provided there.

=over 4

=item os_flavor

We're Unix and Cygwin.

=cut

sub os_flavor {
    return('Unix', 'Cygwin');
}

=item cflags

if configured for dynamic loading, triggers #define EXT in EXTERN.h

};

=item replace_manpage_separator

replaces strings '::' with '.' in MAN*POD man page names

=cut

=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 L<ExtUtils::MM_Unix> to determine if it may be a command.
Otherwise use the tests from L<ExtUtils::MM_Win32>.

=cut

    my ($self, $file) = @_;

    return (substr($filepath,0,length($cygpath)) eq $cygpath)
    ? $self->SUPER::maybe_command($file) # Unix
    : ExtUtils::MM_Win32->maybe_command($file); # 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.

=cut

    $s;
}

=item install

Rebase dll's with the global rebase database after installation.

=cut
