Thanks Duncan,

Actually printf is on the run path already. And from the command line, the
printf command works just fine. The error "File '-c' not found" only
occurs when the command is executed my make.

Thanks for the pointers on '\n' - I was wondering why escaping things
doesn't work as expected. I don't think it's make's fault. From the
command line, too, printf commands seem to ignore '\n', and just take out
the '\'.

I find it hard to believe that this error doesn't come up all the time.
There must be umpteen makefiles for GCC on RISC OS that use echo or
printf, and on my setup at least, they all bomb out with the error message
that is the subject of this thread.
