I have been trying to determine why this does not happen and how to fix it.  I assumed (incorrectly) that it was related to some configuration files, but perhaps it has to do with libtool, collect2 or ld?  Also please note that all these are static libraries because NEXTSTEP does not support building of shared libraries.
