- Fixed: R_GetOneSkyColumn() and R_GetTwoSkyColumns are mulscaling an

unsigned integer that can use all 32 bits. They must therefore use
  the unsigned mul instruction rather than the signed imul instruction.
- Fixed several signed/unsigned comparison and possibly uninitialized
  variable warnings flagged by GCC.
