Subject: [PATCH] Add m4/ax_cc_for_build.m4 for CC_FOR_BUILD
|
||
|
|
MIME-Version: 1.0
|
||
|
|
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit
|
||
|
|
|
||
|
|
CC_FOR_BUILD variable is used in man/Makefile.am.
|
||
|
|
m4/ax_cc_for_build.m4 macro file is missing from autoconf-2.69, thus
|
||
|
|
it is not possible to build indent after regenerating a build script
|
||
|
|
with autoreconf. We need to distribute the macro file in indent.
