When compiling Sage-6.4.beta1 with MPIR-2.7.0-alpha10 on Linux x86_64
with GCC 4.6.4, I get
gcc -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -fPIC

error: command 'gcc' failed with exit status 1
The reason is that you are overloading with "intmax_t" and "long int"
which is the same type.
I don't know if I should blame MPIR, PPL or Sage, but I just let you
know because this worked fine with MPIR-2.6.0.
