+ fix some strict compiler warnings in ncurses library. + modify configure macro CF_HEADER_PATH to not look for variations in the predefined include directories. + improve configure macros CF_GCC_VERSION and CF_GCC_WARNINGS to work with gcc 4.x's c89 alias, which gives warning messages for cases where older versions would produce an error.
