From 16e8d3b92b5e35a5eaee40a7b7fc0279c342886a Mon Sep 17 00:00:00 2001 From: Luke Shumaker Date: Mon, 30 Jan 2017 01:33:24 -0500 Subject: (libretools) Fix bugs in autothing. Some of these are that I hadn't originally designed autothing v3 to work with --warn-undefined-variables. Others are just straight-up bugs from inadequate testing. --- build-aux/Makefile.once.head/00-var.mk | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'build-aux/Makefile.once.head/00-var.mk') diff --git a/build-aux/Makefile.once.head/00-var.mk b/build-aux/Makefile.once.head/00-var.mk index 1f50f21..7c9e6ff 100644 --- a/build-aux/Makefile.once.head/00-var.mk +++ b/build-aux/Makefile.once.head/00-var.mk @@ -1,4 +1,4 @@ -# Copyright (C) 2016 Luke Shumaker +# Copyright (C) 2016-2017 Luke Shumaker # # This program is free software: you can redistribute it and/or modify # it under the terms of the GNU Affero General Public License as published by @@ -20,14 +20,17 @@ define mod.var.doc # Outputs: # Target : `$(outdir)/.var.%` # Directory variable: `at.targets` +# Directory variable: `var.` # # It's a well-known secret that many files generated by a Makefile vary with # the values of particular variables, but that GNU Make can't track these # dependencies.
