Agree. I have tried the 8051 compiler from Dunfield. It is usable, 
BUT it is not near ANSI, and generates about 20 % more code than
the IAR 8051 compiler (www.iar.com). The IAR compiler is fairly
expensive, and very buggy, at least v5.12. It is in my opinion
not worth the money, because of the bugs.

A good compiler to port to other architectures should have extensive
support for optimisation in the early stages of the compiler (low
level opt. is of course architecture dependent), correct error
messages (i.e. a clever parser), and be (near) ANSI.
