that was me.  the problem is make clean removes "?".
(can't remember what "?" is, to find it do "make clean;make -j4", my
machine is wedged at the moment...)

make depend builds "?"
make builds "?", but a different verson than "make depend"!!!
something about what files are around when "?" is built.

I think the solution is to make "make" realize that it needs to "make depend"
before anything else if ".depend" doesn't exist

so as long as you do a "make depend" between any "make clean" and "make"
you are OK
