Adam Strzelecki to SDL This patch significantly speeds up make process (mostly noticeable on MinGW+MSYS) canceling implicit rules for dependencies and Makefile.in that caused lot of unnecessary file checks (in case of Windoze those are pretty slow). See "make -d" before and after applying this patch.
