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>
| #endif
