I want "#define FOO" not "#define FOO 1"

I can put fragment 1 in configure.in to get "#define COLOR_SUPPORT 1" or "#define COLOR_SUPPORT 0" into config.h. However, I'd much rather have "#define COLOR_SUPPORT" or no #define to decide if color will be supported. To me, fragment 2 looks like it would do the trick, however COLOR_SUP
