Michael, 

I have a hypothesis that may explain why attempts to build a DLL fail
on Cygwin when using the GNU build system in the csound module.  Maybe
the reason there are undefined references is simply because the
sources used to build the DLL contain files it should not.  Please
read the definition of libcsound_la_SOURCES in csound/Makefile.am and
elide the names of source files that do not support the implementation
of the Csound API.  Be sure to update your csound sandbox, as I
corrected another error associated with generating DLLs.  I added
-no-undefined to libcsound_la_LDFLAGS.  Thanks.

John

I fixed configure.in.  I wasn't sure about the change requests, so I
made no other changes.
