-- * ext/fiddle/extconf.rb: use pkg_config to find ffi.h. -- * ext/fiddle/extconf.rb: De Morgan's laws. -- * ext/fiddle/extconf.rb: check ffi.h even when pkg-config succeeded. On Debian/lenny, which is a "supported" platform, ffi.h is installed in /usr/include/i486-linux-gnu/. This causes build error when using gcc whose target is not i486-linux-gnu. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_9_2@28420 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
