Actually, zip is not disable. It depends on platform where MC is built.

In a source, this line looks as following:

my $op_has_zipinfo = @HAVE_ZIPINFO@;

The value of @HAVE_ZIPINFO@ is set up in a built time as a result of
'uzip -Z' check. If uzip is installed and supports -Z option in OS
where MC is built then $op_has_zipinfo is set to 1. Else it set to 0.
