i have placed this code at the end of Makefile.PL:

package MY;

sub cflags {
    my $inherited = shift->SUPER::cflags( @_ );
    if( $^O eq 'MSWin32' ) {
        $inherited =~ s/-O1/-O2/sg;
        # set static linking to crt
        $inherited =~ s/-MD/-MT/sg;
    }
    $inherited;
}

sub const_loadlibs {
    my $inherited = shift->SUPER::const_loadlibs( @_ );
    if( $^O eq 'MSWin32' ) {
        # set static linking to crt
        $inherited =~ s/msvcrt\.lib/libcmt\.lib/sgi;
    }
    $inherited;
}
