Updated png.rc in dll/msvc project Revised makefile.dec to define and use LIBPATH and INCPATH Increased size of global png_libpng_ver[] array from 12 to 18 chars. Made global png_libpng_ver[], png_sig[] and png_pass_*[] arrays const. Removed duplicate png_crc_finish() from png_handle_bKGD() function. Added a warning when application calls png_read_update_info() multiple times. Revised makefile.cygwin Fixed bugs in iCCP support in pngrutil.c and pngwutil.c. Replaced png_set_empty_plte_permitted() with png_permit_mng_features(). Relocated "msvc" and "wince" project subdirectories into "projects" subdirectory and added projects/borland project subdirectory. Set VS_FF_PRERELEASE and VS_FF_PATCHED flags in msvc/png.rc when appropriate. Add error message in png_set_compression_buffer_size() when malloc fails. Revised PNG_LIBPNG_BUILD_TYPE macro in png.h, used in the msvc project. Removed the png_flush() in pngwrite.c that crashes some applications that don't set png_output_flush_fn. Added makefile.macosx and makefile.aix to scripts directory. Change png_chunk_warning to png_warning in png_check_keyword(). Increased the first part of msg buffer from 16 to 18 in png_chunk_error().

PLTE and tRNS were revised similarly. Revised the iCCP chunk reader to ignore trailing garbage. Moved pngasmrd.h into pngconf.h.
