Sorry, I don't know which problem you are referring to.

The setup in tests/valid specifically disables the hlc grades that don't
specify agc due the to lack of grade-specific header files. That
won't be a problem if we make these tests only generate .c files.
We can do that both for hlc and llds grades.

I presume you mean adding grade_lib/grade_*.m as arguments
to the invocation of mmc -f in the target for Mercury.modules
in the compiler directory.

Won't that generate .int*, .c, .o and other files for those modules
in grade_lib, instead of compiler?
