/*
 * Dynamic Loader on NetBSD 1.0.
 *
 * 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.
 *
 * agc - I know this is all a bit crufty, but it does work, is fairly
 * portable, and works (the stipulation that the d.l. function must
 * begin with an underscore is fairly tricky, and some versions of
 * NetBSD (like 1.0, and 1.0A pre June 1995) have no dlerror.)
