That's actually not /that/ uncommon. Operations that change an object are
not (side-effect free) functions, so it's just purity if they do not have a
return value.

Would this break existing code?
Source code? Not if you use the PYTHON_NAMESPACE_ONLY trick. Old
programs will receive all old definitions in addition to the new
autoconf symbols, since they didn't #define

Arbitrary, I never have. Different types of my choice, a few times.

Duh, I should of course have said defined(PY_HAVE_ACOSH)

And the puts() should print #define PY_HAVE_WHATEVER 1.
Hopefully there are not too many #defines which would

New submission from Hallvard B Furuseth [EMAIL PROTECTED]:
It can be cumbersome to embed Python in a program which also #includes
a config.h from autoconf, because Python's and the program's autoconf
macros may interfere with each other. Assuming it compiles at all,
both could define the same

You make a good point. I do like being able to say foo.bar=baz rather

For sorting the letter Ä is supposed to be treated like Ae,

Are you sure? Maybe I'm thinking of another language, I thought Ä shold
be sorted together with A, but after A if the words are otherwise

I'm trying to do a whole word pattern match for the term 'MULTX-'
Currently, my regular expression syntax is:

So that regex will match e.g. MULTX-FOO but not
I want to use Python as an extension language in a package
which uses autoconf. That means its and Python's autoconf
#defines can conflict, so I can't safely #include both
Python.h and the package's own include files:-(
Do anyone have a safe way to #include at least object.h
without pyconfig.h?
