So the obvious solution seems to me then to build ncurses twice,

The crashes that will happen when both are loaded in a

AFAICT, the issue is that there aren't enough bits in an int to express
all the button events in the same way as before. The new ABI reshuffles
the bits to make more room.
that, and the extended colors.
It should be possible to make this change in a less invasive way.
Then in that case, it should be possible for someone to submit a patch
which does that.
A possible problem case is: an app built against version X of ncurses
tries to load a shared library built against version X+1 of ncurses.
...and some do, and some don't use libtic and/or libterm.
I didn't see any recent discussion about abi stability
http://lists.gnu.org/mailman/listinfo/bug-ncurses
If there is a realistic problem case, perhaps we should also discuss it there.

I don't recall anyone mentioning it recently (other than this thread, for
example). The ABI=6 code's been there a few years.
