Cosmin Truta b8eb945946 [libpng16] 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).

Changes since the last public release (1.6.14):
Version 1.6.15beta01 [October 29, 2014]
Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x !== 0)"
Simplified png_free_data().
Added missing "ptr = NULL" after some instances of png_free().
Version 1.6.15beta02 [November 1, 2014]
Changed remaining "if (!x)" to "if (x == 0)" and "if (x)" to "if (x !== 0)"
Version 1.6.15beta03 [November 3, 2014]
Added PNG_USE_ARM_NEON configuration flag (Marcin Juszkiewicz).
Version 1.6.15beta04 [November 4, 2014]
Removed new PNG_USE_ARM_NEON configuration flag and made a one-line
revision to configure.ac to support ARM on aarch64 instead (John Bowler).
Version 1.6.15beta05 [November 5, 2014]
Use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING in
example.c, pngtest.c, and applications in the contrib directory.
Avoid out-of-bounds memory access in png_user_version_check().
Simplified and future-proofed png_user_version_check().
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.
Version 1.6.15beta06 [November 6, 2014]
Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING
in the manual, example.c, pngtest.c, and applications in the contrib
directory. It was incorrect advice.
Version 1.6.15beta07 [November 7, 2014]
Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
needed by png_reciprocal2().
Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
png_do_swap().
Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
Version 1.6.15beta08 [November 8, 2014]
More housecleaning in *.h
Version 1.6.15rc01 [November 13, 2014]
Version 1.6.15rc02 [November 14, 2014]
The macros passed in the command line to Borland make are ignored if
similarly-named macros are already defined in makefiles. This behavior
is different from POSIX make and other make programs. Surround the
macro definitions with ifndef guards (Cosmin).
