🚀 go-pugleaf

According to the docs (Preface pg. xv), the limit on parameters to a
#pragma call has been raised to 14, "allowing ALL Amiga library functions
to be called with parameters in registers."  Except that when I used
the #pragma for NewModifyProp(), lc2 gurus (tb reports foo.0000000b).
Take out the pragma, and it compiles fine.  Has anyone else run into this?

============================== cut here ====================================
/*

struct ExtPropInfo {
   struct PropInfo pi;
   UWORD Overlap,        /* Amount of overlap between successive views */
         TotalLines,
         VisibleLines,
         TopLine;
};

void SetPropPosition(window, gadget, topline, refresh)
struct Window *window;
struct Gadget *gadget;
UWORD topline;
short refresh;
{
   UWORD hidden;
   struct ExtPropInfo *epi;

   epi = (struct ExtPropInfo *)gadget->SpecialInfo;

   /* Don't have to update imagery */
   if (epi->TopLine == topline && !refresh)
      return;

   epi->TopLine = topline;

   /* Find the number of hidden lines */
   hidden = max(epi->TotalLines - epi->VisibleLines, 0);

   /* If we can't fill the last display, reduce TopLine */
   if (epi->TopLine > hidden)
      epi->TopLine = hidden;

   if (hidden > 0)
      epi->pi.VertBody = (UWORD)((ULONG)(epi->VisibleLines - epi->Overlap) * MAXBODY
                                      / (epi->TotalLines - epi->Overlap));
   else
      epi->pi.VertBody = MAXBODY;

   if (hidden > 0)
      epi->pi.VertPot = (UWORD)(((ULONG)epi->TopLine * MAXPOT) / hidden);
   else
      epi->pi.VertPot = 0;

   if (window)
      NewModifyProp(gadget, window, NULL, epi->pi.Flags,
                    0, epi->pi.VertPot, 0, epi->pi.VertBody, 1);
}
