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. :-(
