They didn't.

I thought they simply got an offer they couldn't refuse.

Cheers Don...

What do you mean by "very good"? The last time I evaluated IAR for
the PIC18, it generated code that was 50% larger than Hi-Tech (~36K vs
~24K). It was so large that I wasn't able to see if the code actually
worked, because it was too large for the 32K target processor.

I use the Microchip C18 compiler for PIC18 and have had relatively few
problems.

I have used the free Microchip compiler for several projects. So
far I have not come across any major warts except that out of the
box the libraries are compiled for large memory support (24 bit
pointers). First thing I did was recompile for small memory.

You have to remember it is a Harvard architecture and constants
stored in flash cannot be accessed as normal memory. The
compiler will take care of part of this. For the memcpy,
strcpy type library routines you have to remember what memory
the source and destination reside in, and use the proper
library routines.
