     Has anyone out there programmed Color Quickdraw stuff with Think C?
I've been having a problem with getting the compiler to recognize that
color routines such as RGBForeColor and SetCPixel are passed the data type
RGBColor.  For some reason it thinks that it should be a long integer, as
with the (old Quickdraw) ForeColor routine.  Inside Mac vol. 5 states
that these new routines use RGBColor, which contains red, green and blue
values ($0000 to $FFFF).  When I try to compile, though, it gives me the
"Pascal argument wrong size" error.  It compiles fine with a long integer
passed, and runs as if it were using the old Quickdraw routine.
     I've included Color.h and all that, and it recognizes RGBForeColor and
SetCPixel (no linking problems) as valid routines...  What's the deal?
Are the declarations messed up in MacTraps, or am I missing something
obvious?
     Answers of general interest can be posted to the net, otherwise send
me email.
