I'm making the (perhaps artificial) distinction here between a shared library which is suitable for linking into an executable and being loaded by the system's runtime linker, and a DSO which is opened by libpam using dlopen() or equivalent. I leave open the possibility that the two types of shared objects may require mutually-exclusive options when linking on some platforms. Steve Langasek postmodern programmer
