Hi,

I'm seeing the following build error:

n file included from ../.././libcc1/findcomp.cc:20:0:
../.././libcc1/../gcc/config.h:6:23: fatal error: auto-host.h: No such file or
directory
compilation terminated.
In file included from ../.././libcc1/plugin.cc:27:0:
../.././libcc1/../gcc/config.h:6:23: fatal error: auto-host.h: No such file or
directory
compilation terminated.

I've bisected it down to:
