Implementing <stdio.h> requires using <stdarg.h>, so either
cellphones implement <stdarg.h> or nothing runs on it.
Other possibilities are that they'd only implement <varargs.h> instead
(obsolete) or that they have printf() implemented in assembler (obsolete
too). Those are more likely to happen when porting to vintage hardware
using old-fashioned compilers not updated since 1989 or so. It's not the
case for cellphones or even a recent GameBoy-type system.
In short, I don't think it's a valid rationale.

Ok, that's another way to do it. Actually I don't really care how it's
done as long as it's sent to the GUI console correctly and that buffer
overflows are handled properly.

Actually drop the "messy", and the last "else{}" block altogether. I'm
using a printhook to send to the gui layer. What is the point for the gui
console _not_ to use the printhook? who will use the printhook then?

Why yuck? I think it's a feature Pd should have.
On a related note, I also think that commandline options should be
replaced by ";pd"-type messages.
