Subject: [RFA 05/10] Use a stamp file for version.c
Date: Mon, 02 Jul 2018 20:18:00 -0000 [thread overview]
Message-ID: <20180702201824.15005-6-tom@tromey.com> (raw)
In-Reply-To: <20180702201824.15005-1-tom@tromey.com>
This introduces a stamp file for version.c, preventing unnecessary
version.o rebuilds.
2018-07-02 Tom Tromey <tom@tromey.com>
* Makefile.in (clean mostlyclean): Remove stamp-version.
(version.c): Depend on stamp-version.
(stamp-version): New rule, from version.c rule.
