System: Sun 4/490, SunOS 4.1.1, Fortran 1.3.1+patches

I am trying to create a dynamically linked library of some Fortran
math routines.  When I do the 'ld -assert pure-text ...' it complains
about a reference to 'cg89_used' in several of the routines.

The routines were compiled 'fff -c -O -pic -libmil -cg89'.

Questions:
1) Why do only three of 70-odd routines have the cg89_used symbol?  I'm
used to Sun3 systems where just about anything that uses floating
point math would have 'fpa_used' or '68881_used' (according to your
compilation).

2) Why does ld complain -- I thought 'cg89_used' and its cousins were
essentially placeholders.  There are other unresolved externals in
this library, so it can't be just the fact that its not resolved.

3) How should I be going about this?  What can I do to safely
construct a proper dynamic library while making use of the hardware
floatingpoint?

Thanks for any help.  Since this is not likely to be of wide interest,
please reply to me directly & I'll summarize if requested.
