Use `command` instead. - Moved png_check_keyword() from pngwutil.c to pngset.c - Removed LE/BE dependencies in pngvalid, to 'fix' the current problem - in the BigEndian tests by not testing it, making the BE code the same - as the LE version. - Fixes to pngvalid for various reduced build configurations (eliminate unused - statics) and a fix for the case in rgb_to_gray when the digitize option - reduces graylo to 0, producing a large error. - Widened the 'limit' check on the internally calculated error limits in - the 'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error - checks) and changed the check to only operate in non-release builds - (base build type not RC or RELEASE.) - Fixed undefined behavior in pngvalid.c, undefined because - (png_byte) << shift is undefined if it changes the signed bit - (because png_byte is promoted to int). The libpng exported functions - png_get_uint_32 and png_get_uint_16 handle this. (Bug reported by - David Drysdale as a result of reports from UBSAN in clang 3.8). - This changes pngvalid to use BE random numbers; this used to produce - errors but these should not be fixed as a result of the previous changes. - In projects/vstudio, combined readme.txt and WARNING into README.txt - Relocated assert() in contrib/tools/pngfix.c, bug found by American - Fuzzy Lop, reported by Brian Carpenter. - Marked 'limit' UNUSED in transform_range_check().
