It is with LIBRESTRICT=open, but I can reproduce it with open:stat
too...

Yes, it's crude.  I wasn't expecting you to apply this patch; I just
wanted to report that it fixes the compile for me, so this might shed
some light on the problem.

I've tried doing `sh -x ./fixinc.sh', but that didn't reveal any
clues.

I suppose I'll try doing a `sh -x ./fixinc.sh' with
freebsd-x86::cross/gcc, which uses gcc 4.3.2 too (and is succeeding).
Comparing the logs might provide some hints.

Are there any other ways to debug this issue besides shell tracing?
