Hello!
Attached is a patch for handling the case given in #1655 in a less
confusing way (by signalling an error).

Subject: [PATCH] disallow using -c option in csc with multiple files.
Invoking csc with -c and multiple Scheme or C input files results
in any explicit output filenames given being ignored, since there
is an ambiguity for which object file the target filename applies.
C compilers disallow this altogether, so we follow suit.
See also #1655 for more information.
