Well, as far as I know there has to be the symbol table at the
beginning of the library. This table can be created using the s-Option
of ar. Then ld seems to work and you only need to put the libraries
once on the command line. I always create my libraries using

  ar rcs <lib.olb> <files.o>

As far as I remember you can create the symbol table again with a
command like

  ar ts <lib.olb>

This option s replaces ranlib that was used in BSD-like environments.
I believe some people simply forget to put s in their ar-command.
