Subject: [newlib-cygwin] newlib: add AC_CACHE_CHECK sugar around preprocessor checks
Date: Tue, 1 Feb 2022 23:17:50 +0000 (GMT) [thread overview]

commit 041dd7ff265a15096f995396c0005cea19336819
Author: Mike Frysinger <vapier@gentoo.org>
Date: Fri Jan 28 05:17:46 2022 -0500
newlib: add AC_CACHE_CHECK sugar around preprocessor checks
This isn't strictly necessary, but it makes for much clearer logs as
to what the target is doing, and provides cache vars for anyone who
wants to force the test a different way, and it lets the build cache
its own results when rerunning config.status.
