Ok, that's working.

And this much is fine.

However, the auto-build.h is not detecting the all the includes etc.
So while auto-host.h has a #define HAVE_DECL_CALLOC 1, the
auto-build.h has it as 0.

There's nothing in config.log showing a CALLOC of 0.  So where
can I find out what's setting this?

Yeah, I've probably changed something when making all the
additions to get my new target and that is now interfering.
Something similar to that dummy pwait.  Now I've got to find
it and reverse it (or mask it out).

Yes I am.

One other thing I did - I compiled the cross-compiler, and installed it.

Then I wiped out the directory and extracted a fresh version and did
the configure for building the host.  I thought that would make things
clean.  But maybe the previous build had the correct auto-build.h
that I need, and without it I get some sort of dummy auto-build.h?

BFN.  Paul.
