There is no known bug in the 5.02 libraries with %f or %g.  I am still not
convinced you are getting the right printf.  Make sure you are using lcmr.lib
if you are using registerized parameters (-rr).  Use the cross-reference
and map to determine where your printf comes from.  Leave off lc.lib or
lcr.lib from your link line and make SURE that printf doesn't come through
as undefined.  (Actually link with JUST the math library and make sure it
does get defined.)  Are your math libraries linked in before amiga.lib as
well?  (They should be.)  Compile this:

#include <stdio.h>
void main(void) {printf("%g\n", 0.0);}

with the line 'lc -Lm test' and see if it works correctly.  What compile
line are you using?  What math options?  What link line?
