I also have an interest in the answer to this question. I can narrow it
down to the following:
1) Python 2.2.2b1 links find on the particular SCO-Machine I am using.
2) The problem must be somewhere in distutils. Its happening in the run in
distutils/command/build_ext.py. The routine build_extension is called. I
built a print right at the beginning of the routine and another one right
at the end. The warning is coming as it were in the middle of nowhere,
here is the extract from build_ext.py:

    def build_extensions(self):
        # First, sanity-check the 'extensions' list
        self.check_extensions_list(self.extensions)
 
        for ext in self.extensions:
            self.build_extension(ext)
 
    def build_extension(self, ext):
        print "RNS----------------- Begin of Extension ",ext.name
 
 ....
        self.compiler.link_shared_object(
            objects, ext_filename,
            libraries=self.get_libraries(ext),
            library_dirs=ext.library_dirs,
            runtime_library_dirs=ext.runtime_library_dirs,
            extra_postargs=extra_args,
            export_symbols=self.get_export_symbols(ext),
            debug=self.debug,
            build_temp=self.build_temp,
            target_lang=language)
        print "RNS----------------- End of Extension ",ext.name
 
And here is the output:

        find . -name '*.s[ol]' -exec rm -f {} ';'

Now what is being processed that throws up the warning and why?
Considering that the commands, if set off on their own, give no warning.

It is now late in Germany and I am tired and may have missed something
obvious, but I would also be glad of a hint, since, think what I may of
SCO, I would greatly prefer to work with the newest version.
