| * 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.) |
