Bug #1296: [trunk/22981] 64-bit issues on trunk in ext/zlib http://redmine.ruby-lang.org/issues/show/1296 Author: Ollivier Robert Status: Open, Priority: Normal Category: ext, Target version: 1.9.1 ruby -v: ruby 1.9.2dev (2009-03-16) [i386-darwin9.6.0] I've configured Ruby to be compiled in 64-bit mode under OS X 10.5.6 with gcc 4.2. I get the following warnings in ext/zlib which are a bit worrying. gcc-4.2 -I. -I../../.ext/include/i386-darwin9.6.0 -I../../../include -I../../../ext/zlib -DRUBY_EXTCONF_H=\"extconf.h\"
