From 9519cd56d3cb6561a5264ff0ebabb4613f8e42f3 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Thu, 3 Jul 2014 23:19:38 -0400 Subject: [PATCH] move e2fsprogs-specific macros from aclocal.m4 to acinclude.m4 Autoconf says that aclocal.m4 is a machine-generated copy of system-wide macros, whereas acinclude.m4 is for project-specific macros. Reflect this division and ease building by anyone who needs to re-generate the autotooling by splitting AX_TLS and CHECK_GNU_MAKE to acinclude.m4.
