(svn r4183) -Codechange: [Makefile]: removed MANUAL_CONFIG as it's not used anymore
This should hopefully fix the issue where WITH_SDL can be defined while SDL-CONFIG is not
Added an error if WITH_SDL is defined but SDL-CONFIG is not. The same goes for WITH_PNG even though nobody reported this as a problem
removed STATIC_ZLIB_PATH as it turns out that nobody used it
