Is NCURSES_VERSION_PATCH always defined when NCURSES_VERSION is?
If not, code like the following is more robust:

#if !defined(NCURSES_VERSION_PATCH) || NCURSES_VERSION_PATCH < 20040117
# error Old ncurses contain dangerous typedefs, break qemu build (and 
are old)
#endif

Otherwise the patch is good.
