-  Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
-    PNG_ALLOCATED macros to detect deprecated direct access to the
-    png_struct or info_struct members and other deprecated usage in

-  Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,

-    those using compilers other than gcc.
-  Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
-    They should work but still need to be updated to remove
-    references to pnggccrd.c or pngvcrd.c and ASM building.
-  Added README.txt to the beos, cbuilder5, netware, and xcode projects warning
-    that they need to be updated, to remove references to pnggccrd.c and

-    that were detected by the new PNG_DEPSTRUCT macro.

-  Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
-  Removed dependency of pngtest.o on pngpriv.h in the makefiles.
-  Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.

-  Added PNG_PRIVATE macro definition in pngconf.h for possible future use.
-
-version 1.4.0beta97 [November 13, 2009]
-  Restored pngtest.png to the libpng-1.4.0beta7 version.

-  Revised Makefile.in
-
-version 1.4.0beta98 [November 13, 2009]
-  Added the "xcode" project to zip distributions,
-  Fixed a typo in scripts/pngwin.def introduced in beta97.
-
-version 1.4.0beta99 [November 14, 2009]
-  Moved libpng-config.in and libpng.pc-configure.in out of the scripts
-    directory, to libpng-config.in and libpng-pc.in, respectively, and

-  Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt
-  Align row_buf on 16-byte boundary in memory.
-  Restored the PNG_WRITE_FLUSH_AFTER_IEND guard around the call to png_flush()
-    after png_write_IEND().  See 1.4.0beta32, 1.4.0beta50 changes above
-    and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES.  Someone needs this
-    feature but I don't remember who.
-  Make the 'png_jmpbuf' macro expand to a call that records the correct
-    longjmp function as well as returning a pointer to the setjmp
-    jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
