Yes. It's a problem because the scanner assigned types to integer and
floating point constants, but does not have a sense of context so the
negative sign must be stripped off since it could be in the middle of a
math expression. We will need to fix this in gram.y or by using the new
type conversion stuff farther back. But, I don't know how much new type
conversion capabilities there will be until I've tried to address most
of the pieces; still working out lingering problems in the function call
portion.
Will put this one on my list of things to look at.
