Most relevant change: o parse.c: try to include 'posix.mk' the first time .POSIX: is encountered, to allow for beter POSIX compliance. Others o cond.c: make debug logging for comparisons less technical o lst.c: fix mem leak in Lst_Remove o job.c: fix echoing of command with '-' in silent target in jobs mode o var.c: make debug logs more readable prefer 'long long' over 'long' on 32-bit C99 platforms fix crash on .undef of an environment variable

# $NetBSD: varmod-order-numeric.mk,v 1.7 2022/02/09 21:09:24 rillig Exp $
|
|
#
|
|
# Tests for the variable modifiers ':On', which returns the words, sorted in
|
|
# ascending numeric order, and for ':Orn' and ':Onr', which additionally
|
|
# reverse the order.
|
|
#
|
|
# The variable modifiers ':On', ':Onr' and ':Orn' were added in var.c 1.939
|
|
# from 2021-07-30.
|
|
|
|
# This list contains only 32-bit numbers since the make code needs to conform
|
|
# to C90, which does not necessarily provide integer types larger than 32 bit.
|
|
# Make uses 'long long' for C99 or later, and 'long' for older C versions.
|
|
#
|
|
# To get 53-bit integers even in C90, it would be possible to switch to
|
|
# 'double' instead, but that would allow floating-point numbers as well, which
|
|
# is out of scope for this variable modifier.
