Manuel,
I rewrite bb_getopt_ulflags() function for more universal usage.
My version support now:
- options with arguments (optional arg as GNU extension also)
- complementaly and/or incomplementaly and/or incongruously and/or list
options
- long_opt (all applets may have long option, add supporting is trivial)
This realisation full compatibile from your version.
Code size grow 480 bytes, but only coreutils/* over compensate this size
after using new function. Last patch reduced over 800 bytes and not full
applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
trivial addition support long_opt with usage new bb_getopt_ulflags().
Complementaly and/or incomplementaly and/or incongruously and/or list options
logic is not trivial, but new "cut" and "grep" applets using this logic
for examples with full demostrating. New "grep" applet reduced over 300
bytes.
Mark,
Also. I removed bug from "grep" applet.

Please see the LICENSE file for copyright information.
libbb is BusyBox's utility library. This all used to be in a single file
(utility.c to be specific). When I split utility.c up to create libbb, I did
not carefully fix up the copyright and licensing information. I'll do that for
the next release.
For now, just trust me that a bunch of people have worked on this stuff,
and it is all GPL'ed.
