Hi,

yes this is because the definition module paths for system modules are
set at configure time.  You can probably override this (after the copy)
by using -B./path/to/cc1gm2 without the final cc1gm2.  Any chance you
can see what happens if you strace gcc foo.c ?  Ie does it find some
.h files from the correct gcc-lib ?  Or is it using an old version of
gcc-lib ?

Certainly the assignment of path to definition modules makes building
a gm2 package a little tricky and this helped to push me down the pdebuild
route when building debian packages.
