Please inspect and/or show the relevant parts of
  /Volumes/ScratchCS/gcc-4-5-regbuild/gcc/config.log

BTW  - I should have said current trunk:
Updating SVN tree
At revision 151057.
Adjusting file timestamps

======

the configure that's failing is GMP rather than gcc...  maybe I've  
missed a requirement to update?

the essence appears to be this - it looks like some issue with path  
definitions :

| #else
| # include <assert.h>

Maybe http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40950 or similar?
Anyway, the error happens even earlier, probably when it's trying to
find an in-tree C++ compiler.

HTH.  Cheers,

That seems to be it, and the cure is to add --enable-stage1- 
languages=c,c++ (as per the bugreport).

In fact, it seems to effect both Darwin8 & 9 when building in-tree  
GMP (so possibly others too).

The problem appeared between 148251 and 151057 (yeah, a big gap I  
know.. busy with other things).

Note that I haven't changed the GMP - so the fail *is* as a result of  
some aspect of the gcc build process changing.
presumably, most likely the upgrade in auto* tools.

I'll add a comment to the bugreport when the darwin9 build finishes.

thanks again,
Iain

No.  The bug report is from before the autotools upgrade.  The issue
comes from the switch to use C++ as a bootstrap compiler.  I'd guess
r148889,

    ./:
        * configure.ac: Add --enable-build-with-cxx.  When set, add c++ to
        boot_languages.  [...]
