Yes, looks like I last built it back in October of 2011.

Yeah, that sounds familiar (MozillaBuild).

Not surprising as anything 2019 didn't exist back in 2011. :-)

I did figure out ten years ago, and I don't recall it being *that* difficult, but I suppose I could be blocking out a painful memory too. :-)

Might be for the best. That libmozjs source code is not very easy to trouble-shoot even when everything's compiled right with debug symbols and everything (e.g. on Linux).
