improve Matlab compatibility for binary and hexadecimal constants * parser.tst: Update tests for new parsing rules for hex and binary integer literals. * lex.h, lex.ll (handle_number): Now a template with three specializations (binary, decimal, hexadecimal). Eliminate IMAG argument. (HANDLE_NUMBER): New macro. Use it to process binary, decimal, and hexadecimal constants with separate lexer patterns. (Im): Delete pattern macro. (EXPON, NUMBIN, NUMHEX, NUMREAL, NUMBER): Replace with DECIMAL_DIGITS, EXPONENT, REAL_DECIMAL, IMAG_DECIMAL, and DECIMAL_NUMBER for matching decimal numbers and SIZE_SUFFIX, BINARY_BITS, BINARY_NUMBER, HEXADECIMAL_BITS, and HEXADECIMAL_NUMBER for matching binary and hexadecimal numbers. ({NUMBER}{Im}): Delete rule. ({BINARY_NUMBER}, {HEXADECIMAL_NUMBER}): New rules. ({DECIMAL_DIGITS}/\.[\*/\\^\']|{DECIMAL_NUMBER}): New rule to replace {D}{D_}*/\.[\*/\\^\']|{NUMBER}. (make_integer_value): New static function. NEWS: Note change.
