I'm not up to speed on the arguments for why this isn't the default.
Enabling gcj builds libjava by default, and g++ builds libstdc++...

Ah, OK.  That may well have fixed the problem I was experiencing.  At

came across the ADAC documentation in the installation instructions.

I withdraw my objections.  Though the process wasn't as painless as
it could have been.
