Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos)
Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
Added a check for overlength PLTE chunk in pngrutil.c.
Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
Added a warning in png_decompress_chunk() when it runs out of data.
Added PNG_USE_DLL macro.
Revised the copyright/disclaimer/license notice.

upward through 1.0.7beta16 are Y2K compliant. It is my belief that earlier

Assumes that zlib DLLs and LIBs are in ..\..\msvc\win32\zlib
To build:
1) On the main menu Select "Build|Set Active configuration".
Choose the configuration that corresponds to the library you want to test.
This library must have been built using the libpng MS project located in
the "mscv" subdirectory.
2) Select "Build|Clean"
3) Select "Build|Rebuild All"
4) The test results should appear in the "Build" pane of the Output Window.

VII. Y2K Compliance in libpng
May 29, 2000
June 4, 2000
Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
upward through 1.0.7beta15 are Y2K compliant. It is my belief that earlier
upward through 1.0.7beta16 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has three year fields. One is a 2-byte unsigned integer that

libpng and zlib libraries:
libpng1.dll (default version, currently C code only)
libpng1a.dll (C + Assembler version)
libpng1b.dll (C + Assembler debug version)
libpng1d.dll (C code debug version)
libpng1[a-c,e-m].dll (reserved for official versions)

libpng1[n-z].dll (available for private versions)
zlib.dll (default version)
zlib.dll (default version, currently C code only)
zlibd.dll (debug version)
If you change anything in libpng, or select different compiler settings,
please change the library name to an unreserved name, and define
PRIVATEBUILD or SPECIALBUILD accordingly.
DLLFNAME_POSTFIX and (PRIVATEBUILD or SPECIALBUILD) accordingly. DLLFNAME_POSTFIX
should correspond to a string in the range of "N" to "Z" depending on the letter
you choose for your private version.
All DLLs built by this project use the Microsoft dynamic C runtime library
MSVCRT.DLL (MSVCRTD.DLL for debug versions). If you distribute any of the
above mentioned libraries you should also include this DLL in your package.
For a list of files that are redistributable in Visual C++ 6.0, see
