address of an external variable that comes from another DLL. This is a fundamental difference between WIN32 DLLs and Unix DSOs. So, for every SEC_ASN1Template inside of libnss3 that is referenced by other templates outside of libnss3, a new "chooser" function was created that returns the address of that template. For WIN32, the templates outside of libnss3 access libnss3's templates by the chooser function rather than by direct reference. Some simple macros allow Unix to continue to use direct references, avoiding the extra function calls. With these changes, all.sh (qa script) passes all tests on NT with DLLs.
