[fpc-pascal] softfloat bug?

[Henry Vermaak]

hi everyone

fpc with softfloat seems to work quite well on arm (le).  i've run
into a strange problem, though.  i've got code that looks like this:

  writeln(stderr, 'gain is ', round(scan.avge.tip.gain * 100));
  writeln(stderr, 'gain is ', format('%.0f', [scan.avge.tip.gain * 100]));

sometimes i get an eoverflow exception on the second line.  this
depends on the value of scan.avge.tip.gain.  here's a trace - might
not be very helpful:

gain is -10

any help would be appreciated!
