:-) 
I know what you mean.

GCC is not usually suitable for 8 and 16 bit embedded systems. IT is a
generic compiler system that is not usually a patch onthe commercial
ones..

yes.... though some one will now tell us about the 8015 from 197* that
was around for 2.3 years :-)

But is it any good? 

I once had to work on an embedded system using Mod2 a none of the
compilers supported the basic language in the same way.  Let alone
extensions.  It turned out that the most stable compiler was the least
standard :-( 

A theoretically good language is no use at all if the compiler
implementations are no good. 

At least with C there will usually be several commercial compilers and a
multitude of testing and checking tools.  

It's one thing having a compiler but what about the rest. How many ICE
support ADA?
