I have an OpenBSD install handy if that's why you mean. I'll try it out soon.

OpenBSD developers last I checked don't have wordexp() because they consider it a security risk and they dont intend on ever adding it. I actually looked into that in the past myself because I also needed it for something. The best you can do is omit any code relying on wordexp on OpenBSD in specific while not effecting its use on other platforms. There is no clear workaround sadly.
