Subject: [PATCH 1/2] Fix problem on windows

MAX_PATH is defined in stdlib as 260 on windows.
As some source files included stdlib and some not, it made the program crash because of different sizes of the filepath structure.
You can check it with sizeof(filepath) in romfs.c and settings.h.
Tested on MinGW latest update.
