Re: Compiling ncurses-6.1 on OpenBSD

[Robert Smith]

Dear Thomas,

It's interesting to see some new discussion around this whereas I am attempting 
to build it again.

I was just reviewing some of the correspondence from earlier in the year to see 
if there was anything I could do to get some kind of build working. Even ugly.

Is there a work around available that I can test?

-Robert
