Possible spin2cpp glitch

Rayman

Was just trying spin2cpp and it gave a syntax error on this line:

DAT
fname   byte "i"[12],0

but, it doesn't complain if I do it this way:

DAT
fname   byte 105[12],0

Found another thing, this one is really a bug...

I had this in Spin:

    repeat nd  'do dummy clocks
      outa[ClockPin]~~        'toggle clock
      outa[ClockPin]~

But, normally nd==0 and so the the repeat isn't executed.

But, Spin2Cpp turns this into a do loop, which always executes at least once:

      int32_t _idx__0028;
      _idx__0028 = Nd;

      do {

        OUTA = ((OUTA & 0xfffffeff) | 0x100);

        OUTA &= ~(1<<Clockpin);

        _idx__0028 = (_idx__0028 + -1);

      } while (_idx__0028 >= 1);

Thanks for the bug reports, Ray! I'll try to fix these in the next spin2cpp version.
