Here is the details from Apple's Release notes (http://www.opensource.apple.com/darwinsource/10.3/gcc-1495/AppleReleaseNotes.html)
* The -traditional-cpp option has changed. In Apple GCC 3.1 and earlier Apple GCC compilers, -traditional-cpp was used to toggle between the standard GNU GCC preprocessor and Apple's own preprocessor, "cpp-precomp". The GNU GCC compiler interpreted -traditional-cpp differently on all other platforms. Since cpp-precomp has been removed for Apple's GCC 3.3 compiler, the standard GNU meaning of -traditional-cpp has been restored. By default, the GCC 3.3 preprocessor conforms to the ISO C standard. Using the -tradtional-cpp option means the C preprocessor should instead try to emulate the old "K&R C" So, Apple's compilers use these flags: GCC 2.95 uses -traditional-cpp - Apple non-standard interpretation GCC 3.1 uses -no-cpp-precomp GCC 3.3 restored to the standard GCC flag usage Hope that clears things up. ;) Michael On Mon, 21 Feb 2005 11:44:17 +0100, Dalibor Topic <[EMAIL PROTECTED]> wrote: > Riccardo wrote: > > In <[EMAIL PROTECTED]> Dalibor Topic wrote: > > > >>>This might not be necessary on darwin7 since I think Apple changed > >>>the way the compiler works for gcc 3.3.
