Not sure how this would've worked in the past, and not now, but I was
able to make it do the right thing by including the following at the
top of my source file:
#define PILOT_PRECOMPILED_HEADERS_OFF 1
#define _DONT_USE_FP_TRAPS_ 1
Do this before: #include <Pilot.h>
Give it a shot and see if it gives you the results you want... It
seemed to work for me.
Other than that, it may be possible to fix the Metrowerks compiler
and/or the header files to make it work "right", but since this is
only useful in supporting Palm OS floating point on 1.0 devices, and
since 1.0 devices now number less than one or two percent of the
whole installed base, I'm not sure it's worth the effort to fix it
(or for you to support it with a separate build of your app). Move
on to 2.0 as a required base version for your app and you won't have
to even worry about this anymore. [Still, if you insist, the above
should get it working again for you.]
