Thanks. Sometimes NetBSD is just quicker to adopt bleeding edge
features of GNU software;-)

The forced CFLAGS+=-fPIC confuses me. I though that's a measure to the
same effect. I wonder if --disable-multilib should be there or not.

My expectation would be that this fixes a lot.

Whoa! This explains that those are found for you. On Linux, these files
are hidden in private gcc directories, as with the separate
/usr/pkg/gccXX/. Still leaves me to wonder if combinding whatever
version of gcc is in base with gccXX-libjit is right.

It doesn't have to. Mind that I observe only linking failure on
_running_ the conftest program, where it utilizes libgccjit to invoke a
linker. But with the libs in /usr/lib/, it'll find them.

I tend to do that. Maybe something to read later if you have trouble
going to sleep;-)


Alrighty then,
