Ahem on myself.  I should have mentioned I'm using LSC 3.0.  Obviously this
has changed since 2.01.  Perhaps LSC 3.1 will have true ANSI prototypes???
Of course, I'd rather have THINK spend their time on a C++ compiler.

And will the debugger be updated to let you look at all stack frames?  LSC's
is the first symbolic debugger I have seen that only lets you look at the top
frame.  Surely I'm not the only one who digs into calling stack frames in
search of the Last Bug...

Only thy return values.  But what else could a K&R lint do?  A true ANSI C
compiler (when there is such a thing) would have to check parameters as well.

Oh yes.  But at least LSC 3.0 does something with the prototypes it allows!
MPW C (the last non-beta version) would except ANSI prototypes, and then
silently ignore them.  I'm sure this feature was documented too...
