1) OpenBSD is very strict about compliance with standards, so that,
   whereas on my (and I believe most if not all) Linux systems wait.h
   occurs redundantly in /usr/include/ and /usr/include/sys, on
   OpenBSD wait.h is solely in /usr/include/sys and your code will not
   compile unless the `#include<wait.h>' line is removed.  Then `gcc
   -W -Wall' compiles it without complaint.

2) OpenSBD is not so extravagant with the resources allocated to
   unprivileged users (max 128 processes).  But spawning 64 rather
   than 256 children the test is passed with the expected behavior on
   OpenBSD 5.2 GENERIC.MP#368 amd64.

The OpenBSD 5.2 ports include Dillo 2.2 and FLTK2, but I just recently
compiled FLTK 1.3.2 and Dillo 3.0.3 from their unmodified source on
that machine without (IIRC) any errors.  If you were curious more
generally to see how they are modifying the Dillo source, the OpenBSD
patches for Dillo 3.0.3 (the version currently in ports for OpenBSD
5.3) may be found at
