Class or interface `sun.io.CharToByteConverter' not found

[Brad Cox <bcox at virtualschool dot edu>]

Pardon the newbie question but it seems I need help to get started.

I'm trying to compile a working java program to binary with gcj. The 
application relies heavily on AWT and JCE (ABA provider). I hope to handle 
by replacing AWT with a MacOSX InterfaceBuilder frontend in the short run,
  and deal with any JCE issues by hand. But neither seems to be the problem 
here; the compile isn't getting even that far.

> gcj --version
> 2.96

Here's the Makefile I'm using. I'm stale on C style makefiles, so 
suggestions on how to set up Makefiles for gcj would be a big help.

Here's the compile output; source and logfile is below. Apparently 
something (Serializable? ) is pulling in Sun's OutputStreamWriter (which 
does reference CharToByteConverter) instead of the libgcj version which 
doesn't. I thought libgcj would be included automatically.

In the unlikely event it matters, here's the file (one of many) that 
failed:
