Sure.  I don't have access to CVS from this machine... but here is a snippet 
for automake.texi (Program Sources), and maybe similar treatment for the 
Libtool Modules node, with s/lib_LIBRARIES = foo/lib_LTLIBRARIES = mymodule/ 
and s/foo.c/mymodule.c:

If @samp{hello_SOURCES} is not specified, then it defaults to the single
file @file{hello.c}; that is, the default is to compile a single C file
whose base name is the name of the program itself.  In this context,
the base name is always the name that would have gone to the left of
the @samp{_SOURCES} primary, before canonicalization and with any
suffixes replaced with @samp{.c} (This is a terrible default but we
are stuck with it for historical reasons.)
@vindex _SOURCES
@vindex SOURCES

For example if you have the following somewhere in your
@file{Makefile.am} with no corresponding @samp{libfoo_a_SOURCES}:

@example
lib_LIBRARIES = libfoo.a
@end example

@noindent
@file{libfoo.a} will be built using a default source file named
@file{libfoo.c}.

And a new test is attached.

Cheers,
        Gary.
