0f6303301f [libpng16] Fixed pngvalid 'fail' function declaration on the Intel C Compiler. 
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().

503a49458b [libpng16] Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. 2013-11-22 15:16:04 -06:00

c912050a7b [libpng16] Fixed 'minimal' builds. Various obviously useful minimal 
configurations don't build because of missing contrib/libtests test programs
and overly complex dependencies in scripts/pnglibconf.dfa. This change adds
contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.

bd757acf26 [libpng16] Reverted change of ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED 
to PNG_SET_UNKNOWN_SUPPORTED in pngpread.c; it led to the possibility of
calling png_handle_unknown() twice.

7976b3c3e3 [libpng16] Moved prototype for png_handle_unknown() in pngpriv.h outside of 
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
Removed recently-added #ifdef from pngpread.c; moving the prototype
in pngpriv.h fixed the compiler warning that the #ifdef was trying
to solve.

012d36f643 [libpng16] Changed ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED to

fd8bba4b80 [libpng16] Changed NEON implementation selection mechanism to allow assembler 
or intrinsics to be turned on during the build by defining
PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1).  The
default is "undefined" and the build type is selected in pngpriv.h.

34ac3691cb [libpng16] Make autogen.sh work with automake 1.13 as well as 1.14. Do this 
by always removing the 1.14 'compile' script but never checking for it.

236e105170 [libpng16] Simplified error message code in pngunknown. The simplification has 
the useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).
 2013-10-04 20:28:33 -05:00
John Bowler
5b1df53a82 [libpng16] Cleaned up (char*) casts of zlib messages. The latest version of 
the Intel C compiler complains about casting a string literal as (char*), so
copied the treatment of z_const from the library code into pngfix.c

940b37b197 [libpng16] Made changes for compatibility with automake 1.14: 
1) Added the 'compile' program to the list of programs that must be cleaned
       in autogen.sh
    2) Added 'subdir-objects' which causes .c files in sub-directories to be
       compiled such that the corresponding .o files are also in the
       sub-directory.  This is because automake 1.14 warns that the
       current behavior of compiling to the top level directory may be removed
       in the future.
    3) Updated dependencies on pnglibconf.h to match the new .o locations and
       added all the files in contrib/libtests and contrib/tools that depend
       on pnglibconf.h
    4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
       way of handling the dependencies of sources that are machine generated;
       unfortunately it only works if the user does 'make all' or 'make check',
       so the dependencies (3) are still required.
