[SDL] Sint64 problems under KDeveloper

[Tyler Montbriand]

Because KDeveloper compiles under strict ANSI C/C++ by default - the ANSI 
standard not including the 'long long' type - 64-bit integers don't work by 
default under KDeveloper.  I've managed to get it to compile by mucking 
around in makefiles and removing the -ansi flag, but I suspect that will 
vanish in the next 'distclean/rebuild all'.  Has anyone else encountered this 
problem, and if so does anyone know of a better solution?
