The unix linker (ld) is a single pass linker and as such if a module contains an unresolved external reference that module must appear after the caller in the -l sequences. This problem would not happen on the IBM as iewl is a two pass linker. The version of proc.mk in the 7.0.16 version we are using has the duplicate entries as required. Hope this helps - read the details on -l in the cc or ld man pages for a better explanation.
