[It takes a clear mind to make it]

There'd be more to it than that.  At the least you'd need to have the
translator stick casts into every funciton call argument, to deal with
the type conversions that done for you in dpANS.  This would produce
some very ugly Old-C, unless you wanted a much smarter translater that
would only do these casts when necesary.  You'd also need to deal with
preprocessor weirdnesses between dpANSI and say, the UNIX/Reisser CPP.

To a certain degree you'd be writing an ANSI compiler that happened to
spit out C instead of assembler.

Anyone out there:  please post it when you're done (:-).
