- Added dlclose(), dlerror(), dlopen() and dlsym() functions, which are

available only under OS4. There is a variant of dlopen() in libunix.a
  which will perform a path name conversion. Note that these functions
  will not work in the thread-safe variant of the library because it
  would be unwise to tinker with the currently running program's binary.
