Most parallel build problems can be seen on single processor boxes
with a -j3 to -j5 bootstrap. They can usually be identified by the
fact that make -j1 works flawlessly, and a make -j5 doesn't. :-(
If you show us the error in a make -j5, we can probably tell you if
we've seen it before.

Would you mind reposting that patch? I'll definitely give it a try.

make -j1 on the dual-processor box works fine, and also make -j4 on a
similiar single-processor box does (both tested half a dozen times).
My first report is at http://gcc.gnu.org/ml/gcc-bugs/2000-09/msg00354.html ,
but I'm also getting
gmake[4]: *** No rule to make target `genemit.c', needed by `genemit.o'. Stop.
gmake[4]: *** Waiting for unfinished jobs....
gmake[4]: Leaving directory `/files/pfeifer/OBJ-2009-23:12/gcc'
gmake[3]: *** [sparcv9/gmon.o] Error 2
gmake[3]: *** Waiting for unfinished jobs....
./xgcc -B./ -B/sw/test/gcc/SunOS/sparc-sun-solaris2.8/bin/ -isystem
and also different ones. At least one other tester has now been able to
reproduce this problem.
The only difference between my two boxes is the number of processors
and the version of Solaris: 2.8 vs 2.6, so this is either a bug in our
Makefiles(?), a bug in GNU make or in Solaris. :-(

http://gcc.gnu.org/ml/gcc-bugs/2000-08/msg00557.html
It seems that it is expected to patch gcc for parallel build on smp.
BTW, I haven't bootstraped gcc for quite a few days. I don't know
what else is broken now :-).

As the tester in question, I'll post my results for the record. A quick
reminder to all, though, that recursive parallel make handling changed in
gmake 3.79.
Using Solaris 8.1 on a dual-CPU box with gmake 3.77 and -j4, I was unable
to reproduce the problem; current CVS built fine.
Then I remembered that I had forgotten to upgrade my gmake. Once I had
done that, using gmake 3.79.1, the exact same previously-successful source
fails a fresh bootstrap with
No rule to make target `lists.c', needed by `lists.o'. Stop.
The last several lines of the build are included below.

It seems that this problem has been fixed (or ``disappeared'') now, at
least that's what several tests this weekend have shown.
Thanks to you and others who helped with verifying this problem!

Has any of you access to a two-processor SPARC box running Solaris 2.8
(or perhaps 2.7)?
I'm getting weird parallel build failures and would like to know whether
these can be reproduced by someone else using my settings.
(Perhaps this even can be reproduced on a different two-processor box.
If someone would like to give it a try, please contact me directly.)

Parallel build has been broken for a while. I reported it and provided
a kludge. But very few people seem to care.
