What do you mean by “short-circuits”? Is the -fPIC flag not provided on the link line? It’s there, but the debug flags override it and the resulting objects are not position-independent?

I don’t see why PIC and debug symbols should be mutually exclusive (in that one would cause the other to be ignored), but I don’t understand that stuff well enough to say for certain.

As long as configure2 doesn’t remove the -fPIC flag somewhere when optimizations are turned off, I don’t know why it wouldn’t work. I’ve actually done that myself in the recent-ish past and it’s worked fine.

All the best,
