[clug] discovering gcc "<xxx.h>" (system) include directories

[steve jenkin]

I've been using a Macports gcc for i386-elf to cross-compile Linux kernel.
Note: this is a non-standard gcc with very non-standard paths (in
/opt/local) compiled in. [and incorrectly]

I'm at a loss as to how to find what include directories are compiled
into a version of 'gcc'.

I've used Makefile settings to over-ride whatever defaults it uses, but
I'm left underwhelmed...

Anyone fought this dragon and know how to discover the magic?
