=head1 NAME

ExtUtils::MM_Win95 - method to customize MakeMaker for Win9X

=head1 SYNOPSIS

  You should not be using this module directly.

=head1 DESCRIPTION

This is a subclass of ExtUtils::MM_Win32 containing changes necessary
to get MakeMaker playing nice with command.com and other Win9Xisms.

=head2 Overriden methods

Most of these make up for limitations in the Win9x command shell.
Namely the lack of && and that a chdir is global, so you have to chdir
back at the end.

=item dist_test

&& and chdir problem.

=cut

sub dist_test {
    my($self) = shift;
    return q{
disttest : distdir
	cd $(DISTVNAME)
	$(ABSPERLRUN) Makefile.PL
	$(MAKE) $(PASTHRU)
	$(MAKE) test $(PASTHRU)
	cd ..
};
}

=item subdir_x

&& and chdir problem.

Also, dmake has an odd way of making a command series silent.

=cut

sub subdir_x {
    my($self, $subdir) = @_;

    # Win-9x has nasty problem in command.com that can't cope with
    # &&.  Also, Dmake has an odd way of making a commandseries silent:
    if ($DMAKE) {
      return sprintf <<'EOT', $subdir;

subdirs ::
@[
	cd %s
	$(MAKE) all $(PASTHRU)
	cd ..
]
EOT
    }
    else {
        return sprintf <<'EOT', $subdir;

subdirs ::
	$(NOECHO)cd %s
	$(NOECHO)$(MAKE) all $(PASTHRU)
	$(NOECHO)cd ..
EOT
    }
}

=item xs_c

The && problem.

=cut

sub xs_c {
    my($self) = shift;
    return '' unless $self->needs_linking();
    '
.xs.c:
	$(PERLRUN) $(XSUBPP) $(XSPROTOARG) $(XSUBPPARGS) $*.xs > $*.c
	'
}


=item xs_cpp

The && problem

=cut

sub xs_cpp {
    my($self) = shift;
    return '' unless $self->needs_linking();
    '
.xs.cpp:
	$(PERLRUN) $(XSUBPP) $(XSPROTOARG) $(XSUBPPARGS) $*.xs > $*.cpp
	';
}

=item xs_o 

The && problem.

=cut

sub xs_o {
    my($self) = shift;
    return '' unless $self->needs_linking();
    '
.xs$(OBJ_EXT):
	$(PERLRUN) $(XSUBPP) $(XSPROTOARG) $(XSUBPPARGS) $*.xs > $*.c
	$(CCCMD) $(CCCDLFLAGS) -I$(PERL_INC) $(DEFINE) $*.c
	';
}

=item clean_subdirs_target

&& and chdir problem.

=cut

sub clean_subdirs_target {
    my($self) = shift;

    # No subdirectories, no cleaning.
    return <<'NOOP_FRAG' unless @{$self->{DIR}};
clean_subdirs :
	$(NOECHO)$(NOOP)
NOOP_FRAG


    my $clean = "clean_subdirs :\n";

    for my $dir (@{$self->{DIR}}) {
        $clean .= sprintf <<'MAKE_FRAG', $dir;
	cd %s
	$(TEST_F) $(FIRST_MAKEFILE)
	$(MAKE) clean
	cd ..
MAKE_FRAG
    }

    return $clean;
}


=item realclean_subdirs_target

&& and chdir problem.

=cut

sub realclean_subdirs_target {
    my $self = shift;

    return <<'NOOP_FRAG' unless @{$self->{DIR}};
realclean_subdirs :
	$(NOECHO)$(NOOP)

	-cd %s
	-$(PERLRUN) -e "exit unless -f shift; system q{$(MAKE) realclean}" $(FIRST_MAKEFILE)
	-cd ..
RCLEAN

    }

    return $rclean;
}


=item max_exec_len

Win98 chokes on things like Encode if we set the max length to nmake's max
of 2K.  So we go for a more conservative value of 1K.

=cut

sub max_exec_len {
    my $self = shift;

    return $self->{_MAX_EXEC_LEN} ||= 1024;
}


=item os_flavor

Win95 and Win98 and WinME are collectively Win9x and Win32

=cut

sub os_flavor {
    my $self = shift;
    return ($self->SUPER::os_flavor, 'Win9x');
}
