[ros-diffs] [tkreuzer] 48128: [RBUILD] For amd64 builds, invoke wrc directly, instead of using gcc to preprocess the files. The reason is that newer gcc versions (like 4.5.0) don't support multiline continuation (backslash-newline) except for preprocessor directives, but that breaks wine resource strings. This might have to be done for i386 builds too, sooner or later.
