i tried it but except it doesn't work i didn't gather much information 
and tftpd has no option to work in foreground and debug option.
same for tftp client which has only verbose/trace option but there is no 
way to enable/disable tsize/blk/blk2/... to know if an option works.
I suppose all these ones work in compatibility mode so don't use tsize 
and others.

I try to add a debug trace with macro (some simple print to file) but i 
get nothing except main beginning ...

i investigate little but i manage to compile with the following changes 
in MCONFIG CFLAGS:
i delete: -D_XOPEN_SOURCE
and add: -DHAVE_U_SHORT -DHAVE_U_LONG
now it compiles (i haven't test it for now)
(note for archives: problem was seen from sys/socket.h and arpa/inet.h 
header, error about u_short and some others)

i'll test it to know if it works but i thing it would be best if base 
openbsd could support tsize option in tftpd ...
