Would that be for compiling the kernel with XLC or for user space 
applications
running in the simulated linux environment?

If I understand you correctly that this is about applications using the 
callthru inlines, then they should use a differrent header file anyway. 
Note
that the version I posted has everything wrapped inside '#ifdef 
__KERNEL__',
so user applications can not use it.

That is absolutely intentional, as user applications should never directly 

include kernel header files anyway. The correct solution would be to 
either
include  a copy of the header file in the application using it or to
provide a separate package that installs a header file for user space into
$PREFIX/include. Shipping the file with mambo should be ok as well, but I
would suggest to make a clear separation of header files for use on the 
host
side (the one running the simulator binary) and header files for the 
target
side.
