Thanks for pointing this out. Actually it is not such a great loss because
the header files are not expected to be used -- they are only for debugging

I've tried

This cannot be done from the command line alone. The way it has to be done
has been explained several times in the mailing list and is documented,
partially, in the manual http://ecls.sourceforge.net/new-manual/re55.html

Because they are not needed. A shared library only exports one function,
the init function, whose name can be customized, but normally takes the
form init_dll_FILENAME(int argc, char **argv)
