For two installations (host GCC, and AVR-GCC) which are somewhat
comparable (both are prefixed to /usr/local, but differ in some other
configure options), it looks like this:

AVR-GCC:

ignoring nonexistent directory 
"/usr/local/lib/gcc/avr/4.8.3/../../../../avr/sys-include"
#include "..." search starts here:
#include <...> search starts here:
 /usr/local/lib/gcc/avr/4.8.3/include
 /usr/local/lib/gcc/avr/4.8.3/include-fixed
 /usr/local/lib/gcc/avr/4.8.3/../../../../avr/include
End of search list.

host GCC:

#include "..." search starts here:
#include <...> search starts here:
 /usr/local/lib/gcc47/gcc/x86_64-portbld-freebsd10.0/4.7.4/include
 /usr/local/include
 /usr/local/lib/gcc47/gcc/x86_64-portbld-freebsd10.0/4.7.4/include-fixed
 /usr/include
End of search list.

The "avr" part (before the version number) vs. the
"x86_64-portbld-freebsd10.0" are what always distinguishes both
installations.

(Ivaylo, better subscribe to the list in order to not miss
replies.)
