Right.  I was thinking of -F.

Ah.  It's been a while since looking at docs for the -F flag.  Bits of  
info get lost in my brain due to lack of use.

Or -F would not be needed at all using one of the default paths:

TCLINCDIR =
TKINCDIR =
TCLTKLIBPATH =
TCLTKLIBS = -framework Tcl -framework Tk

We would need a flag in platform.make saying that we're using  
framework headers, so they'll get properly included in GRASS sources.

#ifdef TCLTKFRAMEWORK
#include <Tk/tk.h>
#else
#include "tk.h"
#endif

Got it.  Until I forget from lack of memory excercise.
