[m-users.] mmc --debug and mdb usage problems

[Razetime]

I used --grade as instructed, using asm_fast.gc.decldebug.stseg from the list:

$ mmc --output-libgrades|sort
asm_fast.gc
asm_fast.gc.decldebug.stseg
asm_fast.gc.memprof
asm_fast.gc.prof
asm_fast.gc.profdeep.stseg
asm_fast.par.gc.stseg
hlc.gc
hlc.par.gc

And this is the error I got after attempting a build:
$ mmc --grade asm_fast.gc.decldebug.stseg --make a07
Making Mercury/int3s/a07.int3
Making Mercury/ints/a07.int
