Apple didn't leave out any declarations.  GetGrayRgn is implemented with
glue, not INLINEs, thus the code is supplied at link time from the
Interface.o file.  When you include Windows.p, GetGrayRgn ends up having
a declaration in the INTERFACE, but no code in the IMPLEMENTATION section
of your unit.  Since you have an IMPLEMENTATION section, Pascal complains
when it can't find the code for the declared function.
