New patch for cgi-lib

[Robert Watson]

Recent versions of gcc are more picky than older versions, especially with 
warnings on.  The attached minor patch to cgi-lib.h allows it to play more 
nicely in more recent C development environments.

BTW, I notice there is a new web site and distributor for cgi-lib, who in 
return for fixing a minor bug or two (apparently) has decided to convert it 
from public domain to GPL.  I assume that the choice to not upgrade has long 
since been made, and trust it will remain that way. :-)
