Subject: bug#46578: 28.0.50; configure.ac warnings with autoconf 2.71
Date: Tue, 16 Feb 2021 23:52:13 +0000 [thread overview]
Message-ID: <7d716ca6-38d5-7c2e-cda6-c6531881d525@gmail.com> (raw)
In GNU Emacs 28.0.50 (x86_64-w64-mingw32)
Repository revision: cead0ea38e3e15a544f7374b2e831623bda37f1d
Repository branch: master
Building from a clean tree, I observe the following warnings:
$ ./autogen.sh
Checking whether you have the necessary tools...
(Read INSTALL.REPO for more details on building Emacs)
Checking for autoconf (need at least version 2.65) ... ok

configure.ac:1770: no prerequisites. If you truly need to test whether
configure.ac:1770: something passes the preprocessor but not the compiler,
configure.ac:1770: use AC_PREPROC_IFELSE.)

You can now run './configure'.
Perhaps some adjustment is needed for autoconf 2.71.
