ExtUils::MM_Unix, etc...). It also provides a convenient alias via the MM class (I didn't want MakeMaker modules outside of ExtUtils/). This class might turn out to be a temporary solution, but MM won't go away. =cut { # Convenient alias. package MM; our @ISA = qw(ExtUtils::MM); sub DESTROY {} } sub _is_win95 { # miniperl might not have the Win32 functions available and we need # to run in miniperl. my $have_win32 = eval { require Win32 }; return $have_win32 && defined &Win32::IsWin95 ?
