Do you know if it is now possible to build OS9 binaries with the OSX gcc?
That would be a great thing for J3: it needs to be compiled with gcc,
but the MPW/GCC for OS9 is old and buggy...

(The MPW/GCC sourcetree is available at 
http://irafs1.ira.uka.de/~marcus/j3/3.0Alpha7MTJ3.11j-SRC.sit.bin

but it´s somewhat out of date (based on 3.0Alpha7...). It contains 
Makefiles for building a squeak-vm without j3 with gcc on MacOS9.)

That´s simple: It´s an awk script:

marcus at wombat:~ $ ./gnuify interp.c >ginterp.c

that simple. This can be done automatically from the makefiles
(look at the unix-makefiles or the MPW-Makefile (strange syntax). 

The script uses gawk. OSX as a BSD-Unix doesn´t have this, so you
need to get gawk. Or use "awk -f gnuify", but it might be only compatible
with GNU-awk.
