bug#6812: 24.0.50; Inadvertant name capture (more information)

[Jan Djärv]

It is a monumental stupidity in the ncurses header file, almost criminal.
On Mandriva there is an #ifdef __INTERNAL_CAPS_VISIBLE around
these #defines, but I see not all distributions have them (Suse and Fedora
does not for example).

I checked in a fix.

Thanks for investigating this.
