I took a break from my fiddling with the OPT make/configure variable when I discovered the problems with out-of-tree builds. Andrew got that fixed a couple days ago, so I revisited my changes. I'd like to check them in, but should probably wait until Guido bundles 2.3a1. Changes are to these files:

configure.in (and configure, of course)
setup.py
Makefile.pre.in
Misc/NEWS

There are some structural changes in configure.in that make it worth a careful look-see. In particular, I hope I haven't bolluxed up Martin's SCO changes from September (I can't test on that platform).

Here's the new text from Misc/NEWS:

On systems which build using the configure script, compiler flags which used to be lumped together using the OPT flag have been split into two groups, OPT and BASECFLAGS. OPT is meant to carry just optimization- and debug-related flags like "-g" and "-O3". BASECFLAGS is meant to carry compiler flags that are required to get a clean compile. On some platforms (many Linux flavors in particular) BASECFLAGS will be empty by default. On others, such as MacOSX and SCO, it will contain required flags. This change allows people building Python to override OPT without fear of clobbering compiler flags which are required to get a clean build.

Everything passes on both MacOSX and Mandrake 8.1 from CVS as of a few minutes ago.

I uploaded a new context diff to SF so people can eyeball it, though I'll wait for Guido to say "check it in". There's one itty-bitty change to setup.py that's unrelated. It adds the fink directories /sw/lib and /sw/include to the relevant search lists when building on Darwin.
