Well the STANDARD_INCLUDE_DIR constant isn't even used by gcc-4.7.0, so
I've already dropped that from the jh branch:
http://www.linuxfromscratch.org/~jhuntwork/sysroot/chapter05/gcc-pass2.html
The CROSS_SYSTEM_HEADER_DIR is used for pass1 gcc and
NATIVE_SYSTEM_HEADER_DIR is used for pass2. If the configure switch you
propose does effectively the same thing for pass2, I don't mind using it.
What about pass1? Is there a corresponding switch? I haven't
investigated 4.7.0 too deeply yet.
