You can use libraries as intermediate steps:

        cslopt -a -o templib1.cmxa <many .cmx files>
        cslopt -a -o templib2.cmxa <more .cmx files>
        cslopt -o myexec templib1.cmxa templib2.cmxa <remaining .cmx files>

This takes a little longer to link because of the extra I/O involved
with building the libraries, but it should work.

Modern Unix systems set the ARG_MAX limit so high (128 kbytes under
Linux, 40 kbytes under OSF1) that I was hoping this would not be necessary.
