Hi Buddabing, just downloaded all the new files and created a fresh source directory and I get the same error compiling.

mingw32-make: *** [obj/mame/cpmaker/libs/magick/cache.o] Error 1
I didn't have to mess with any files and I left the makefile alone which looked correct and it compiled well all the way to cache.c again. I'm sure this is something I'm doing wrong because I've never compiled before but I can't figure this one out.
