\subsubsection{Borland C++}
This subsection describes the necessary steps to use Distutils with the
Borland C++ compiler version
5.5.\footnote{Check
\url{http://www.borland.com/bcppbuilder/freecompiler/} for download}
%Should we mention that users have to create cfg-files for the compiler
%see also http://community.borland.com/article/0,1410,21205,00.html
First you have to know that the Borland's object file format(OMF) is
different from what is used by the Python version you can download
from the Python web site. (Python is built with Microsoft Visual C++,
which uses COFF as object file format.) For this reason you have to
convert Python's library \file{python20.lib} into the Borland format.
You can do this as follows:
\begin{verbatim}
coff2omf python20.lib python20_bcpp.lib
\end{verbatim}
The \file{coff2omf} program comes with the Borland compiler. The file
\file{python20.lib} is in the \file{Libs} directory of your Python
installation. If your extension uses other libraries (zlib,...) you
have to convert them too.
The converted files have to reside in the same directories as the normal
libraries do.
How does Distutils manage to use these libraries with their changed
names? If the extension needs a library (eg. \file{foo}) Distutils
checks first if it finds a library with suffix \file{_bcpp}
(eg. \file{foo_bcpp.lib}) and then uses this library. In the case it
doesn't find such a special library it uses the default name
(\file{foo.lib}.)\footnote{This also means you could replace all
existing COFF-libraries with OMF-libraries of the same name.}
To let Distutils compile your extension with Borland C++ you now have
to type:
\begin{verbatim}
python setup.py build --compiler=bcpp
\end{verbatim}
If you want to use the Borland \Cpp{} compiler as default, you should
consider to write it in your personal or system-wide configuration
file for Distutils (see section~\ref{config-files}.)

\subsubsection{GNU C / Cygwin / MinGW32}
This section describes the necessary steps to use Distutils with the
GNU C/C++ compilers in their Cygwin and MinGW32
distributions\footnote{Check
\url{http://sources.redhat.com/cygwin/} and
\url{http://www.mingw.org} for more information}.
\XXX{For a Python which was built with Cygwin, all should work without
any of these following steps.}
For these compilers we have to create some special libraries too.
This task is more complex as for Borland's C++, because there is no
program to convert the library (inclusive the references on data structures.)
First you have to create a list of symbols which the Python DLL exports.
(You can find a good program for this task at
\url{http://starship.python.net/crew/kernr/mingw32/Notes.html}, see at
PExports 0.42h there.)
\begin{verbatim}
pexports python20.dll >python20.def
\end{verbatim}
Then you can create from these information an import library for gcc.
\begin{verbatim}
dlltool --dllname python20.dll --def python20.def --output-lib libpython20.a
\end{verbatim}
The resulting library has to be placed in the same directory as
\file{python20.lib}. (Should be the \file{libs} directory under your
Python installation directory.)
If your extension uses other libraries (zlib,...) you might
have to convert them too.
The converted files have to reside in the same directories as the normal
libraries do.
To let Distutils compile your extension with Cygwin you now have to type
\begin{verbatim}
python setup.py build --compiler=cygwin
\end{verbatim}
and for Cygwin in no-cygwin mode\footnote{Then you have no POSIX emulation
available, but you also don't need \file{cygwin1.dll}.} or for MinGW32 type
\begin{verbatim}
python setup.py build --compiler=mingw32
\end{verbatim}
If you want to use any of these options/compilers as default, you should
consider to write it in your personal or system-wide configuration file
for Distutils (see section~\ref{config-files}.)

cygwin/mingw32 and bcpp format, see

and for the missing header files of the in python2.0 included tcl/tk,
