I would prefer something like:
allegro/
src/
keep this clean from build files please
SConstruct
scons/
unix.scons
mingw.scons
vc.scons
misc.scons
util.scons
linux.scons
alsa.scons
x11.scons
...
I.e., keep all the src directories clean of build files, have a single
SConstruct file in the top dir, and put all helper scripts into a scons
dir (which may be hierarchical itself if it makes sense). So there's not
so much clutter.

The .s files should be compiled with gcc -x assembler-with-cpp. Not sure
if scons does dependencies for them, but a custom scanner (or just some
Depend() calls) would be quite trivial for them.

Heh, yes. Actually, if we first have a unix build only, that would be a
good first step.

Dunno, Peter Wang gave me this link on allegro.cc - so Guido van Rossum
himself seems to be among the people who don't like it:
