Current problems:
-double/float is mostly a kludge
-build-grub-mkfont
-nm on OpenBSD doesn't accept same options as GNU one.

Only the first problem still remains.

I have just tested the compilation of the latest revision (5148) and confirm 
that it compiles OK!
There is a warning about random generator not being secure in 
util/grub-mkpasswd-pbkdf2.c, which may be supressed by adding "&& ! defined 
(__OpenBSD__)" to the defines list.

To do this we need a confirmation that reading from /dev/urandom is
indeed the right way to access PRNG on OpenBSD and that it gives us
cryptographically good random.
What would you consider adequate confirmation?

I understand there was a problem with random and urandom in
OpenBSD up to 4.9, though arandom was good.

calomel.org asserts that, as of OpenBSD 5.1, all their random devices
use the arc4 library;  /dev/urandom now gives as good as /dev/arandom.

The following 'ent' analysis is presented for /dev/arandom:
-----------------------------------------------------
user@machine:  ./ent output 
Entropy = 7.999956 bits per byte.

Optimum compression would reduce the size
of this 419430400 byte file by 0 percent.

Chi square distribution for 419430400 samples is 257.21, and randomly
would exceed this value 44.95 percent of the times.

Arithmetic mean value of data bytes is 127.5178 (127.5 = random).
Monte Carlo value for Pi is 3.144255776 (error 0.08 percent).
Serial correlation coefficient is -0.000120 (totally uncorrelated = 0.0).
