Summary: odbc module not portable

Initial Comment:
I'm interested in using the ODBC module with unixODBC
and/or iODBC on Linux.  I've gotten it to work, after a
fashion, with Python 2.3.3 and unixODBC 2.2.8 on SuSE
Linux 8.2.  I'd like to know how receptive you would be
to portability patches.

One category of changes conditionally compiles the
Windows-specific things: windows.h, __declspec, etc.

Another category of changes removes the few C++ things
in an otherwise C-compatible module: declarations,
comments, map(), etc.

This is mostly in odbc.cpp, but there are also a few
changes to dbi.h and dbi.cpp.

The datetime module's C API is not fully baked, so I guess
we're stuck with DBI, for a while.  I submitted patches
#956244 and #956247 to remove Windows and C++ dependencies.

BTW, I think I omitted the -u option on some of the patches
I submitted.  Let me know if you have any problems with them.

I've submitted patches #956091, #956093, and #956094.  The
first patch has an attachment that includes the latter two,
because they don't apply cleanly together.

The only essential change to dbi.h is CALLCONV.  There's
also a warning in the initialization of noMethods in dbi.c.
 I'm not submitting a patch at this time, because I'd like
to experiment with a DBI-less ODBC module.

I'm not sure how to test ODBC without a DBMS and a DSN, so I
don't have any tests, right now.  There has been some
discussion on the unixODBC list about developing an ODBC
test framework.

I would be happy to support that - particularly if the
changes came with a few tests - we don't have any at the
moment, and that alone would be a big improvement.
