Detecting GCC vs. Clang/LLVM

The crux of the matter is that Clang also defines the __GNUC__ macros, which took me an hour or so to debug. So if you need a GCC vs. Clang (vs. LLVM-GCC) switch, you _must_ check for Clang/LLVM first.

#if defined __clang__ /* The Clang frontend to LLVM (Clang) */ #define COMPILER "Clang" #elif defined __llvm__ /* The GCC frontend to LLVM (LLVM-GCC) */ #define COMPILER "LLVM-GCC" #elif defined __GNUC__ /* The GNU GCC compiler */ #define COMPILER "GCC" #else #define COMPILER "Unknown" #endif

This is the Fullscreen Toolbar I have written for Q. The version for Q is slightly modified to work with the host-cocoa part [see in svn: http://www.kju-app.org/proj/browser/trunk/host-cocoa/FSControls].
