I've been trying to build a c++ Xcode 2.2 project under gcc 3.3 in order to ship a c++ based solution to customers running MacOS versions prior to 10.3.9.

The project builds fine with gcc 4, but now I always get this error:

"gcc-3.3: cannot specify -o with -c or -S and multiple compilations"

The strange this is, I can build some projects with gcc 3.3 (using the GCC_VERSION build setting) but not wxWidgets (which other projects depend on). And even projects which work have both "-o" and "-c" as options to gcc, so the error message seems very misleading.

Please post the compiler invocation line from the build transcript for the file that generates this error. There's no way to tell what's happening without seeing the input parameters to the compiler.
