I'm currently working on an ANSI-C back-end.  Progress is slow, but
there is some.  My current schedule looks like this:

1) Implement generation of C declarations.  I want to be able to put
an Oberon-2 module though the compiler and get correct C files
containing all global declarations (but without a single statement).

2) Extend `make' to call the C compiler.

3) Add modifiers for declarations and type constructors to model C
types.  With this I'll be able to write interface modules describing
access to arbitrary C libraries.

4) Translate GSA code into C statements.

The first point is tricky, 2) and 3) shouldn't be that hard, and I
only have fragmentary ideas how to do 4) .  Time will tell, I guess.  ;-) 

None of the above should effect the front-end.
