$ python setup.py build_ext --help
...

Options for 'build_ext' command:
   ...
   --compiler (-c)      specify the compiler type
   ...
   --help-compiler      list available compilers

$ python setup.py build_ext --help-compiler
List of available compilers:
   --compiler=bcpp     Borland C++ Compiler
   --compiler=cygwin   Cygwin port of GNU C Compiler for Win32
   --compiler=emx      EMX port of GNU C Compiler for OS/2
   --compiler=mingw32  Mingw32 port of GNU C Compiler for Win32
   --compiler=msvc     Microsoft Visual C++
   --compiler=mwerks   MetroWerks CodeWarrior
   --compiler=unix     standard UNIX-style compiler

These are the only options the distutils provide for --compiler, and 
setuptools doesn't currently offer any way to extend this.  (Although if 
somebody wanted to contribute a mechanism to do so based on entry points, 
that would be way cool.)
