Hi Charles, can you try enabling the two typedefs at ~ line 67 in
nsterm.h to see if the first batch of errors go away?

I guess it’s possible the second typedef should be an NSUInteger
instead of a plain int. I just took a guess and that silenced the
errors when building under GNUstep.

Probably we should be using one function for recent macOS’s and
another for old ones. Yamamoto san had something to say about it, but
I’ve not had a chance to investigate:
