* Dynamic Loader on Alpha OSF/1.x
24
* this dynamic loader uses the system dynamic loading interface for shared
25
* libraries (ie. dlopen/dlsym/dlclose). The user must specify a shared
26
* library as the file to be dynamically loaded.
30
* In some older systems, the RTLD_NOW flag isn't defined and the mode
31
* argument to dlopen must always be 1. The RTLD_GLOBAL flag is wanted
32
* if available, but it doesn't exist everywhere.
33
* If it doesn't exist, set it to 0 so it has no effect.
