[6.0] fails to compile on macOS with Clang 8.1.0

[Denis Davydov]

Dear all,

On the fresh Clang 8.1.0 on macOS 10.12.4 with XCode 8.3, ncurses fails to 
compile with the error below. 
Most likely something is screwed up yet again by Apple’s clang, but it would 
still be nice to have a workaround.

Kind regards,
Denis.
