The natural hook is monkeypatching distutils.spawn.spawn, I think... Actually:
from distutils import ccompiler # the module
ccompiler.spawn = my_new_posix_spawn

pid = os.fork()
if pid = 0:
err = open("filename.ext", 'w')
os.dup2(err.fileno(), sys.stderr.fileno())
try: spawn(cmd)
finally: err.close()
else:
os.wait(pid)
err = open("filename.ext", 'r')
try: data = err.read()
finally: err.close()
Something like that... Actually, we should modify _spawn_posix() in
distutils.spawn adding the os.dup2 stuff. Right now I'm very busy to
implement it, sorry.
