34 <PRE>><i>DL_LAZY is only needed for future compatibility, as stated in the
35 </I>><i>OpenBSD
3.0 man page.
36 </I>><i>man dlopen reports:
37 </I>><i>"The path argument can either be an absolute pathname or it can be of
38 </I>><i>the form ``lib
<name
>.so[.xx[.yy]]'' in which case the same library
39 </I>><i>search rules apply that are used for ``intrinsic'' shared library
40 </I>><i>searches. The second argument currently has no effect, but should be
41 </I>><i>set to DL_LAZY for future compatibility.
"
43 Then it sounds like OpenBSD is already doing things the wrong way,
44 so I'll probably just disable dynamic modules entirely for it.
