I have a 64-bit perl that likes to give warnings (I'm doing a use warnings;) that greater than 32bit numbers are non-portable every time I have one typed in. I realize that they are not portable and would like to disable this specific warning, but am unsure how to do it. I've looked into "no warnings;", but it's too broad. I suppose I'll have to use: no warnings "X"; where X is the string I need to find. How do I go about solving this?
