First, to Larry: If you can find the time, please post the Compress code
to comp.binaries.

Second, to Bob: Yes the APW C has a more or less complete Unix library as
far as file calls (open,creat,fopen, etc), memory allocation (malloc,
calloc) and printing (printf, scanf, etc) are concerned.  The libraries
implement GS toolbox calls to prodos, the memory manager and text manager.
If you use the libraries, though, the code has to run in native mode and
stdin, stdout and stderr require running under the APW shell, so it will not
be portable to any other Apple II other than the GS.

The time required to load the compiler and to link can be quite long even
for extremely short programs and with a hard disk, so using APW C requires
a lot of patiences or a very large ramdisk (2 meg total memory or so).
