Glenn Randers-Pehrson
eeab1cfefc [libpng17] Eliminated the PNG_SAFE_LIMITS macro and set default limits in 
pnglibconf.dfa, that can be reset by the user at build time or run time.
This provides a more robust defense against DOS and as-yet undiscovered
overflows.

8cfee5fa78 [libpng17] The macros passed in the command line to Borland make were ignored if 
similarly-named macros were already defined in makefiles. This behavior
is different from POSIX make and other make programs.  Surround the
macro definitions with ifndef guards (Cosmin).

f87df31c8c [libpng17] Fixed GCC unsigned int->float warnings. Various versions of GCC 
seem to generate warnings when an unsigned value is implicitly
    converted to double. This is probably a GCC bug but this change
    avoids the issue by explicitly converting to (int) where safe.
  Free all allocated memory in pngimage. The file buffer cache was left
    allocated at the end of the program, harmless but it causes memory
    leak reports from clang.
  Fixed array size calculations to avoid warnings. At various points
    in the code the number of elements in an array is calculated using
    sizeof.  This generates a compile time constant of type (size_t) which
    is then typically assigned to an (unsigned int) or (int). Some versions
    of GCC on 64-bit systems warn about the apparent narrowing, even though
    the same compiler does apparently generate the correct, in-range,
    numeric constant.  This adds appropriate, safe, casts to make the
    warnings go away.
