 * Dynamic Loader on Alpha OSF/1.x
 * this dynamic loader uses the system dynamic loading interface for shared
 * libraries (ie. dlopen/dlsym/dlclose). The user must specify a shared
 * library as the file to be dynamically loaded.

 * In some older systems, the RTLD_NOW flag isn't defined and the mode
 * argument to dlopen must always be 1.  The RTLD_GLOBAL flag is wanted
 * if available, but it doesn't exist everywhere.
 * If it doesn't exist, set it to 0 so it has no effect.
