convert HAVE_GCC handling to modern GCC release numbering: - HAVE_GCC=5 is now the default (vs. HAVE_GCC=53 we've been using for GCC 5.4 and GCC 5.5.) - remove some more GCC 4.8 code. we don't support GCC 4 here. - adjust set lists to gcc=5 from gcc=53. add some basic HAVE_GCC=6 handling (totally unused so far.) 2018-02-02 04:02:39 +03:00			`# $NetBSD: Makefile,v 1.16 2018/02/02 01:02:39 mrg Exp $`

Use POSIX regular expression routines. Remove TODO file, as I've allready done everything that there was to do. 1993-06-14 23:56:06 +04:00			`PROG= expr`
reimplement expr using lexical parser generated by yacc highlights: * / is treated correctly depending upon context (addresses PR # 10995) * use 64 bit arithmetic, so expr is able to process integer values from -(263) to (263 - 1) * checks for integer over- & underflows added * error messages improved, more error checking added add AUTHOR section to manpage add BUGS section, and mention possible drawbacks with other expr implementations XXX the old expr treated empty string in arithmetic expressions as if it was 0 XXX this behaviour has been retained 2000-09-19 21:20:00 +04:00			`SRCS= expr.y`

for GCC 5.3 pass -fwrapv as this relies upon well-defined integer overflow. 2016-04-01 11:19:31 +03:00
