Hi,
In the newest autoconf 2.66, AC_CONFIG_SUBDIRS warns when it is invoked with
more than one directory. But this way of invoking it is supported, see the doc:
-- Macro: AC_CONFIG_SUBDIRS (DIR ...)
Make `AC_OUTPUT' run `configure' in each subdirectory DIR in the
given blank-or-newline-separated list. Each DIR should be a
literal ...
How to reproduce:
===================== configure.ac ====================
AC_INIT
AC_CONFIG_SUBDIRS([lib src tests doc])
AC_OUTPUT
=======================================================
With autoconf 2.65:
$ autoconf
With autoconf 2.66:
$ autoconf
configure.ac:2: warning: AC_CONFIG_SUBDIRS: you should use literals
../../lib/autoconf/status.m4:1098: AC_CONFIG_SUBDIRS is expanded from...
configure.ac:2: the top level
Looks like a regression to me.
