I did this today.
I downloaded and built GNU make 3.81 and put it in my PATH.
Then I did "make -j2" builds in the gcc directory of each revision.
I also ran "touch Makefile.in" and then "make -j2" again.
I didn't see any hangs. So, at least for me, the branch seems safe.
Anybody else can easily try it.
I do need to make another revision of the series, though. I'd forgotten
why gdb has this "POSTCOMPILE" step, but I saw the answer while
re-reading the old thread: it avoids an atomicity problem if gcc is
interrupted while writing the .Po file. I'll send the new series soon.
