Summary: distutils support for swig is under par

Initial Comment:
To my delight there is support for swig built into
distutils.  However a few problems exist with the support.

- there is no way to specify any extra flags to the
swig command (I need -I/usr/include -DHAVE_LONG_LONG);
- swig generates two files, the XXX_wrap.c file which
is turned into a _XXX.so file, and a XXX.py file. 
distutils only deals with the XXX_wrap.c file.

I have no suggested fix for these problems, but
problems they are.

(Python from CVS HEAD on Fedora Core 2).

Hmm, you can't really call that "decent swig support" then,
can you?
If this "solution" were properly documented (in a place one
would notice when trying to create a setup.py to do swig!)
then it wouldn't be too much of a problem, but I wouldn't
know where that would be.

So, if my change doesn't cause any detrimental effects I'd
much rather see it fixed that way.

Haven't read the original problem (I don't use swig myself),
but if changing the order of the sub_commands list than it
can as well be done in the setup script by installing a
custom build command.

I just came up with a possible solution:

In command/build.py change the order of the
build.sub_commands list and put the entry for build_ext
before build_py.

The question is, does this cause a problem for anybody?

Part of the problem described here (the extra options that
need to be given to swig) is solved by [ 1046644 ] improving
distutils swig support (2).  However, the other part is
still a problem.
