In CGI will be with you, always, I used the content of CGI.pm to extract all four letter bits from it. I took care of line endings using chomp. Still, on different platforms, with the same version of CGI.pm, I get different results.

Why is it that the same version of CGI.pm is different on different platforms? For further checking:

Naturally, this calculus has problems, since line endings do vary between Win32 and Unix... But still, there are differences. Why?

Update: So I am stupid. tye suggested to use diff, which showed me the differences: some hardcoded globals, like $TempFile::TMPDIRECTORY do change between OSes...

Tool used: perl -p0777MDigest::MD5=md5_hex -e '$_=md5_hex$_'
