3167541570 [libpng16] Fixed 'prefix' builds on clean systems. The generation of pngprefix.h 
should not require itself.

f1c0678c16 [libpng16] Fixed non-configure builds (don't include pngprefix.h in them) 2012-01-31 07:37:46 -06:00
John Bowler
42369ccd85 [libpng16] Added symbol prefixing that allows all the libpng external symbols 
to be prefixed (suggested by Reuben Hawkins).  This is work in progress that
breaks some non-configure builds.

572b078d8c [libpng16] Cleaned up pngpriv.h to consistently declare all functions and data. 
Also eliminated PNG_CONST_DATA, which is apparently not needed but we
can't be sure until it is gone.

40ca77a721 [libpng16] Improved pngstest speed by not doing redundant tests and add const 
to the background parameter of png_image_finish_read. The --background
option is now done automagically only when required, so that commandline
option no longer exists.

aaf1179ec1 [libpng16] Added two images to contrib/pngsuite (1-bit and 2-bit transparent 
grayscale), and renamed three whose names were inconsistent with those in
pngsuite/README.txt.

a23f3dbcb6 [libpng16] Freeze libtool files in the 'scripts' directory. 
This version of autogen.sh attempts to dissuade people from running it when
it is not, or should not, be necessary.

da2194c0d5 [libpng16] Rewrote autogen.sh to run autoreconf 
instead of running tools one-by-one.

1eb2c48458 [libpng16] Updated configure.ac from autoupdate: added --enable-werror option. 
Also some layout regularization and removal of introduced tab characters
(replaced with 3-character indentation).  Obsolete macros identified by
autoupdate have been removed; the replacements are all in 2.59 so
the pre-req hasn't been changed.  --enable-werror checks for support
for -Werror (or the given argument) in the compiler.  This mimics the
gcc configure option by allowing -Werror to be turned on safely; without
the option the tests written in configure itself fail compilation because
they cause compiler warnings.

8fb6c6a9b3 [libpng16] Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived) 
compiler issues slightly different warnings from those issued by the
current vesions of GCC. This eliminates those warnings by
adding/removing casts and small code rewrites.

0522f269e0 [libpng16] Update png_err() to use new typecast. 2011-12-29 10:02:24 -06:00
John Bowler
fcd301daed [libpng16] Changed png_memcpy to C assignment where appropriate. Changed all 
those uses of png_memcpy that were doing a simple assignment to assignments
(all those cases where the thing being copied is a non-array C L-value.)
Added some error checking to png_set_*() routines and removed the
reference to the non-exported function png_memcpy() from example.c. Fixed
the Visual C 64-bit build - it requires jmp_buf to be aligned, but it had
become misaligned.

John Bowler
4f67e40898 [libpng16] Add 'const' to png_structrp arguments of png_set_*() APIs. 
Because these APIs store to the png_info they can take a
 png_const_structrp now that the error routines also accept
 one of these.

f87ef8bcb5 [ibpng16] Moved AC_MSG_CHECKING([if libraries can be versioned]) later

a5bf4e3767 [libpng16] Initialize "passes" variable in pngread.c to avoid compiler warning. 
It was not actually possible to use it uninitialized but gcc doesn't know that.

5d56786eff [libpng16] Implemented 'restrict' for png_info and png_struct. 
Added new "png_structrp" typedef. Because of the
way libpng works both png_info and png_struct are always accessed via a
single pointer.  This means adding C99 'restrict' to the pointer gives
the compiler some opportunity to optimize the code.  This change allows that.

29fca0d497 [libpng16] Enabled png_get_sCAL_fixed() if floating point APIs are enabled. 
Previously it was disabled whenever internal fixed point arithmetic was
selected, which meant it didn't exist even on systems where FP was available
but not preferred.

df477e4652 [libpng16] Eliminated png_info_destroy. It is now used only in png.c 
and only calls one other internal function and memset.
