-----------------------+--------------------------------
 Changes to OS X 10.11 render GCC's Objective-C compiler useless.  However,
 I want to compile the main part of Python in GCC (because my C++ / Fortran
 Cython modules use GCC).

 I tried to build Python (via MacPorts) using Clang for Objective-C and GCC
 for C/C++.  The environment upon running ./configure included:

   CC='/Users/rpfische/macports/mpgompi-4.9.3/bin/gcc-mp-4.9'
   CXX='/Users/rpfische/macports/mpgompi-4.9.3/bin/gcc-mp-4.9'
   OBJC='/usr/bin/clang'
   OBJCXX='/usr/bin/clang++'

 HOWEVER... the build still tried to use GCC to compile Objective-C, and
 failed miserably:



 :info:destroot /Users/rpfische/macports/mpgompi-4.9.3/bin/gcc-mp-4.9 -pipe
 -Os -arch x86_64 -Wno-unused-result -fno-common -dynamic -DNDEBUG -g
 -fwrapv -O3 -Wall -Wstrict-prototypes -o FileSettings.o -c
 ./FileSettings.m
 :info:destroot /usr/include/objc/NSObject.h:22:4: error: unknown type name
 'instancetype'
 :info:destroot  - (instancetype)self;
 :info:destroot     ^
 ...
