Re: Boost.Python support for Py 2.1 rich comparisons

A while ago Nick Sauter posted patches for Boost.Python to enable
support for Python 2.1 Rich Comparisons:

http://groups.yahoo.com/group/boost/message/12147

To integrate Nick's patches, I have created a new CVS branch

    boost_python_richcmp

in the directories root/boost/boost/python and root/boost/libs/python.
The code in this branch is tested with:

    Python 1.5.2:
      vc60.mak
      mingw32.mak
      linux_gcc.mak
      tru64_cxx.mak
      irix_CC.mak

    Python 2.1:
      linux_gcc.mak
      tru64_cxx.mak
      irix_CC.mak

    Python 2.1.1c1:
      vc60.mak

Everything is fine, except for the vc60 warning messages that are
attached. I had similar messages before with my application code.
Therefore I believe that the messages below have nothing to do with 
the
Rich Comparison patches. The warnings that I got when compiling my
application never bothered me too much, but it does not look good if
the examples that come with the package generate warnings. What I do
not understand is why comprehensive.cpp does not generate similar
warnings. Is there a trick that I do not know about? What do people
think about using pragmas to get rid of the warnings?

Feedback is appreciated. I hope to be able to merge the modifications
into the trunk before the next Boost release.
