NCurses determines the presence of the <stdbool.h> header during its
own build time but the result is used in a public header <curses.h>.
It cannot be assumed that the application building against this public
header <curses.h> also uses the same compiler NCurses was built with.
Hence the public header <curses.h> has to perform an own in-place check
for <stdbool.h>. This way NCurses can be build with OpenPKG's GCC 3.x
while an application could build against the provided <curses.h> with an
arbitrary C compiler (usually a non-GCC 3.x vendor compiler!).
