68cb0aaee3 [libpng16] Implement eXIf chunk support 2017-07-13 11:22:48 -05:00
John Bowler
72d07d3202 [libpng16] Removed one of the GCC-7.1.0 'strict-overflow' warnings that 
result when integers appear on both sides of a compare.  Worked around the
  others by forcing the strict-overflow setting in the relevant functions to
  a level where they are not reported.
Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
  the space.
Worked around some C-style casts from (void*) because g++ 5.4.0 objects
  to them.
Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
  overflow' check that is on by default with -Wall -Wextra.
