   1 /*
   2  * HPUX 10.x stubs to implement dl* in terms of shl*
   3  *
   4  * Not needed for later versions; HPUX 11.x has dlopen() and friends.
   5  *
   6  * configure also needs to be faked out.  You can create a dummy libdl.a
   7  * with stub entries for dlopen, dlclose, dlsym, and dlerror:
   8  *
   9  *      int dlopen() { return(0);}
  10  *      int dlclose() { return(0);}
  11  *      int dlsym() { return(0);}
  12  *      int dlerror() { return(0);}
  13  *
  14  * This has not been tested; I just read the manual page and coded this up.
  15  *
  16  * According to the ld manual page, you need to link bash with -dld and add
  17  * the -E flag to LOCAL_LDFLAGS.
