Exactly. /usr/include on a Unix system does not move with the
compiler. It's always /usr/include whether the compiler is built for
/usr or not. $prefix/$target_alias/include moves with the compiler.
A sysroot may or may not (the configure script decides at build time;
only configure scripts inside $exec_prefix move with the compiler).
Some handholding may be required if you want /mingw/include to move
with the compiler, which it doesn't on other systems.
The code that handles the relocation is not terribly complicated.
