Just did a very quick test without looking at any code or really knowing
what is going on.

The standard setup compiles out of the box (because it ignores nio and
swing).

Removing java/nio and gnu/java/nio from the lib/standard.omit file gives
lots and lots of errors.

Running the gen_nio.sh script in the lib directory seems to fix some
files and then running make gives the following errors:

So it seems you forgot to check in some classes (SocketAddress and
AbstractChannel at least).

The gen_nio.sh script adds some java/nio files and modifies some
gnu/java/nio files. This does not interact nicely with CVS (the working
directory now contains files that CVS thinks are modified or new) . You
might want to rename the input files to X.java.in and look at how to
generate the actual X.java files with configure(.in) like
gnu/classpath/Configuration.java is. Although that might not be the most
oppropriate solution in this case.
