Fascinating.  Maybe 2.2.1 was what was running on the MBP from which  
I retrieved the "good" SDCC 2.4.0.  I will have to revert back the  
MBP (from 2.4 to 2.2.1) and the Intel-iMac further (from 2.3 to  
2.2.1) and see if that makes any difference - hopefully Monday (Oct 16).

I was able to boil down the runtime error in SDCC 2.6.0 (i.e.  
compiling C code into FPGA code using SDCC) using about 30 lines of  
GR code.  I've submitted the various findings including that code  
(with FSF header) to the DarwinPorts folks, who seem intrigued.

You and the general GR community (esp OSX users) are welcome; it  
continues to be a goal of mine to maintain functionality on OSX.   
Sometimes that means going on these wild goose chases, and finding a  
work-around but not a solution.  Given the time-constraints in my  
life, I'm OK with that. - MLD
