    Another "free" Obj-C implementation is available via anonymous ftp on
    ghost.dsi.unimi.it (yeah, it is in Italy!!), in the file pub/objective-C.tar.Z.
    It does contains a translator, a debugger and a runtime library (I think). 

We don't need the translator or the debugger, but we could use the library.
Would somebody like to adapt it to work with GCC?

Some of the library probably consists of class definitions, and those
should not need to be changed.  But the message dispatch part of the
library might need to be changed.  There is also the question of how
to represent the data structures that are used for dispatching at run
time, in order to make message dispatch fast.  It looks like part of
this is written in assembler, which is a problem; we need a version
written in C so it can be portable.
