Understand.  On Linux here I don't get the warnings either, but
another of our developers gets them on FreeBSD.  I'll have him do a
cvs update and get a report back from him.  I'll let you know what
he comes back with.  Thanks!

Actually as I recall the combination of "-W and -Wall" triggers all
of those warnings, and "-Wno-unused-parameter" or "-Wno-unused" gets
rid of those.  We had to add a test to our acinclude.m4/configure.ac
in order to see which of those last two parameters the compiler
likes so that we get a clean build on either compiler.

Understand.  Thanks for helping to clean things up a bit.  Our users
appreciate the professional look-and-feel of the compile without the
extra warnings.
