Nice trick to diagnose gcc search paths

Recently I needed to use a compiler as part of an sdk and needed to point it to the correct sysroot. For some reason the --sysroot flag did not work correctly. To inspect what was going on in gcc 'mind' a colleague told me about a "trick":

gcc -o  ./g.c -E  -P  -v -dD
