I backed up to 1.44, but I still see the same problem. And it stands to=20=

reason: my find_module_file()
call was a replacement for os.path.join(moddir, filename). And with=20
moddir being an absolute path
this will also return an absolute path.

I am tempted to think that this problem has always existed, but has=20
gone unnoticed until now.
Now that I know about the problem it clears up some strange behaviour=20
I've seen in the past.
I would love to see this fixed, but I'm afraid I'm not the person to do=20=

it. Distutils
never ceases to amaze me, and it's path-mangling tricks are beyond me.=20=

I'm pretty sure that
if we somehow stuff "../Modules/regexmodule.c" (assuming we're building=20=

in a subdir of the main dir)
into the list of module sources we'll get something like=20
build/tmp.blabla/../Modules/regexmodule.o
for the object filename.

Does anyone else feel up to fixing this?
