Comment (by leif):
Replying to [ticket:13948 jpflori]:
> There are two problems with the MPIR `configure` script for Clang:
>
> 1) It uses `__builtin_malloc()` which Clang doesn't have, which is an
MPIR upstream bug (up to and including MPIR 2.6.0). The spkg simply
removes this test.
>
> 2) The "long long reliability" test fails with a linker error. This
looks like a Clang bug.
The latter one apparently now hits GCC (5.0.1 RC1) as well... B)
(From `config.log` it also seems that the `__builtin_alloca()`
availability test fails for a different reason, but that's harmless.)
