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.
