The following are the table of contents of "clib" as supplied by DRI.
It is created by UNIX nm with my comments appended.

Note: the subroutines are also found in s.o, lib[e|f].a and
    pseudo-subroutines of one type is found as macros in *.h files,
        (assert() has bugs)
    but pseudo-subroutines of another type i.e. asm() etc. are too
    useful to be documented.
       UNIX ld requires space(s) after -u option, but DRI's lo68 does not.
