I am converting some MPW C code from v.2.02 to v.3.0.
The much tighter type-checking is a constant frustration
to my fast and loose programming style.  One particular
problem is with CopyBits.

eg.
PixMapHandle mypixhandle;
.
.
  CopyBits(*mypixhandle, &(((GrafPtr)wind)->portBits),
            &((*mypixhandle)->bounds),&((*mypixhandle)->bounds),
            srcCopy, 0L);

This compiles and works OK in MPW 2.02, but won't compile
in MPW 3.0 because of a type mismatch between formal and actual
parameters in the first argument *mypixhandle.  I've tried
several variations of this, but nothing seems to compile.
The documentation in IM seems to indicate that CopyBits
should take bitmaps and pixmaps with no problem.

Could someone please clue me in as to how to fix this???

Thanks,
