I don't remember, and I don't have any of that stuff left.

Somebody else will provide them, and you will still get complaints. I
also get them. Fortunately there is a standard answer to send out.

But that will add the argument for all platforms. I need to specify
compilation flags separately for each platform/compiler. I might even
want to compile some modules with the new Intel compiler for Linux.

For all extension modules - I need to specify different flags for each
extension module, in one case even for a single source code file.

My current solution is to build everything with distutils and then
recompile the critical modules manually in the spec file.
