Asking gcc for the include directory location?

[Toralf Lund]

Is there any way I can get gcc to tell me where the "normal" include 
directory is located? I mean, for my system's native compiler, this 
directory is "/usr/include", while on e.g. my arm-coff cross-gcc, it's 
"/usr/arm-coff/include". Is there any way to ask the compilers to print 
out these values? If not, how about the full "built-in" include path?

I've searched the docs for this, but wasn't able to find anything. The 
"-print-search-dirs" option is of course related to this, but doesn't 
mention include files, as far as I can tell.
