17878c6e65 [libpng15] Work around compilers that don't support declaration of const data. 
Some compilers fault 'extern const' data declarations (because the data is
not initialized); this turns on const-ness only for compilers where
this is known to work.

4fa96a42f7 [libpng15] Fixes for C++ compilation using g++ When libpng source is compiled 
using g++. The compiler imposes C++ rules on the C source; thus it
    is desireable to make the source work with either C or C++ rules
    without throwing away useful error information.  This change adds
    png_voidcast to allow C semantic (void*) cases or the corresponding
    C++ static_cast operation, as appropriate.

0a521d3785 [libpng15] Installed more accurate linear to sRGB conversion tables. 
The slightly modified tables reduce the number of 16-bit values that
convert to an off-by-one 8-bit value.  The "makesRGB.c" code that was used
to generate the tables is now in a contrib/sRGBtables sub-directory.

07772cba07 [libpng15] Fixes for multiple calls to png_read_update_info. 
These fixes attend to most of the errors revealed in pngvalid, however doing
the gamma work twice results in inaccuracies that can't be easily fixed.
There is now a warning in the code if this is going to happen.

751561218f [libpng15] Constant changes for 64-bit compatibility (removal of L suffixes). 
The 16-bit cases still use "L" as we don't have a 16-bit test system.

f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.

88b77cc6f3 [devel] Remove png_snprintf, add formatted warning messages. 
This change adds internal APIs to allow png_warning messages to have parameters
 without requiring the host OS to implelment snprintf.  As a side effect the
 dependency of the RFC1132 code on stdio is removed and PNG_NO_WARNINGS does
 actually work now.
