Building Kawa under Windows (Cygwin) won't compile

[Jocelyn Paine <popx at pop3 dot ifs dot org dot uk>]

Just installed Cygwin on my NT system and tried building Kawa 1.6.94
from the sources under it. Running ./configure appears to work,
and creates the Makefiles. However, make fails with a load of compilation
errors part of the way through. Some of these are at the end of the
message.

Now, I've actually had this before. When I tried building 1.6.94
for the first time, in June, I didn't know what the .java.in files were,
so posted a query here and got told what they were. I then preprocessed
them to .java files, applying the appropriate options, and tried
compiling. I got the same compilation errors as I'm getting now under
Cygwin. At the time, I thought I must have done something wrong, but
the fact that I'm getting these errors by two different routes is
suspicious. It also suggests that whatever's going wrong isn't Cygwin's
fault. The distribution I'm using is the 1.6.94 gzipped tar from the Kawa
FTP site.
