There are a number of other options as well.  I'd hate to think that it's
necessary to hard-code all of the ones that will have to be handled
specially.

Though, I suppose you could specify   ruler=0 instead of -ruler.  It would
do the same thing (with the current implementation)

getopt_long() does work, but it's NetBSD's implementation, not GNU's.
There's a listing of the differences between them on the following page:

That's the one I grabbed.

Now that I've gotten it to compile, I see that you're overriding lib5250's
keyboard handling?   If I type a key in a field that's supposed to be
uppercase-only, it shows up as lowercase then converts to uppercase when I
hit enter.

I can type letters in numeric fields -- although it stops me after the
first letter...   then error reset doesn't work, you have to hit Ctrl-R
instead of error reset -- and then it doesn't clear the message line, so
you have to just know that pressing ctrl-r worked, despite that error
reset didn't. :)

Can I ask why you rewrote that section of display.c/dbuffer.c instead of
using the tried-and-true code?  Why reinvent the wheel?!   If there was
something lacking in lib5250, why not help improve it instead of replacing
it?

I also see that you're using the GPL.  The GPL is incompatible with
OpenSSL, so the rest of TN5250 uses the LGPL.  If you use GPL, we won't be
able to distribute x5250 together with lib5250 -- just a warning.
