Could you please elaborate a bit on the reasoning behind
deprecating using .compiler for the compiler instance ?

The code did work before, so I'm not sure why you are trying
to fix something that wasn't really broken.

With the change you:

 * make the code more complex just to be able to raise
   a warning

 * introduce an cross-version incompatibility for tools
   using build_ext: they will now have to use .compiler
   for Python 2.3-2.6 and .compiler_obj for 2.7 and up

Wouldn't it be better to either leave things are they have
been for years (without problems) or find another solution ?
