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

annotate Python/errors.c @ 29877:72cbc41ccc2f legacy-trunk

Fix [ 771097 ] frozen programs fail due to implicit import of "warnings". If the initial import of warnings fails, clear the error. When the module is actually needed, if the original import failed, see if it has managed to find its way to sys.modules yet and if so, remember it.
