   It is bug in Linux libraries! They tricked you to think it is right way,
but it is actually wrong way. FreeBSD (in this aspect) is better, more
strict (there are aspect where Linux clearly wins :).
   Compile Zope with gcc -funsigned-char on FreeBSD.

           Programmers don't die, they just GOSUB without RETURN.
