fcntl is not supported on win32 (see perlport).

You might try using Win32API::File or simply try printing 

sub _is_writable {
    my $fh = shift;
    return eval { defined print { $fh } ''; };
}

though that may not be desireable.

update: It just dawned on me that printing on a CLOSED filehandle is different error, than simply a filehandle thats not opened for writing, in which case you want to use the fileno function.

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
