Ah, earlier I said that within the context how kwset uses obstack, it is perfectly proper to fix it like the patch in question did, but the upstream already using size_t changes the picture quite a bit. I do not mind updating our copy of obstack, but make sure you pick the version with license compatible with ours. Thanks.
