### Some makes, like Ultrix's make, complain if you put a comment in
### the middle of a rule's command list!  Dummies.

### The flags for optimization and debugging depend on the
### system, so take an ordinary CFLAGS value and choose the
### appropriate CPP symbols to use in ymakefile.
### If you have a problem with cc -E here, changing
### the definition of CPP above may fix it.
