cpython-lru_cache-weakref: Python/compile.c annotate

annotate Python/compile.c @ 9049:cbf72b2210ae legacy-trunk

Comment out the print statement about underflow. (This only seems to happen when you use a non-keyword argument after a keyword argument, and in this case you also get a syntax error. I fully suspect that the underflow is caused by the code that stops generating code when it detects the syntax error, but I can't find the culprit right now. I know, I know.)
