I have the same problem under SGI and my fix is to edit the few files
with problems and break out the expression with the "ambiguity" in
several statements. That is not pretty and I was waiting for a compiler
upgrade to see if it would fix it.

Example from BMPReader.cxx

      tmp = self->GetFile()->tellg();
      tmp += streamSkip0;
      self->GetFile()->seekg(tmp, ios::beg);

I was able to do a full compile after editing these files. (SGI Octane
CC 7.3)
