Sorry about the duplicate in comp.sys.amiga. I hit "reply" and amiga-relay only
 sends to comp.sys.amiga.  Now back to our regulary scheduled posting...

Lattice uses a bultin function to get arround this problem in printf.
I quote from the Lattice manual, _Lattice C Compiler_ version 4.0

"     printf

When this function is called, the compiler examines the formatting string:

*  When it is a constant string with no substitutions, the compiler changes the
   printf call to a _write call.
*  When it is a constant string AND only contains %s, %d and p% formats a call
   is made to _tinyprintf "

Disclaimer:  All typos are assumed to be mine, not the manual's.

Further they say they may do similar tricks for scanf, sprintf and fprintf but
upon checking my 5.0 manual I don't thing they have done this to date.
