I will try the new patch tonight.

The one the night before had some new errors but it was still not 
chosing the right toolchain as we know.

The good news is that with clang/llvm we eliminated the errors:
     LLVM-Unit :: 
ADT/Release+Asserts/ADTTests/HashingTest.HashCombineBasicTest
     LLVM-Unit :: ADT/Release+Asserts/ADTTests/HashingTest.HashValueStdPair


In particular, check mips-cs.cpp and mips-fs.cpp.

When built with gcc 4.7:

Failing Tests (11):
     Clang :: Analysis/crash-trace.c
     Clang :: Driver/mips-cs.cpp
     Clang :: Driver/mips-fsf.cpp

     LLVM :: CodeGen/Generic/2009-03-17-LSR-APInt.ll
