Fixed bug 944 Tatu Kilappa 2010-02-11 12:13:20 PST When compiling with -Wconversion, gcc complains about a cast in SDL_endian.h that might change the result as we are casting from an int into an Uint16. This is of course not visible unless we are on a non-x86 platform where the assembler is not available. While it's not really an error, the warning is really annoying. To fix, change SDL_endian.h line 87 to: return(Uint16)((x<<8)|(x>>8)); Thank you.
