------- Comment #4 from wilson at gcc dot gnu dot org 2007-11-16 22:37 -------
This problem occurs if you accidentally run
../gcc/gcc/configure
instead of
../gcc/configure
I've tried looking at make -d output, and there isn't enough info there to see
what is going wrong. In the second case, the implicit rule
build/gen%$(build_exeext) is found. If the first case, the implicit rule is
not found, and hence we perform no action when making build/genmodes, resulting
in a non-existent file when we later try to run it.
