To make use of GCC specific features, use the __GNUC__ macro:

<pre>
#ifdef __GNUC__
...
#endif
</pre>

You can also grep the code for __GNU to find out existing samples to learn from.

To make use of LLVM/Clang specific features, use the [http://clang.llvm.org/docs/LanguageExtensions.html Clang language extensions].
