Because we use a macro to test for the specific autoconf version:
aclocal.m4:
5 m4_define([GLIBC_AUTOCONF_VERSION], [2.69])
6 m4_if(m4_defn([AC_AUTOCONF_VERSION]), GLIBC_AUTOCONF_VERSION, [],
7 [m4_fatal(m4_flatten(
8 Exactly version GLIBC_AUTOCONF_VERSION of Autoconf is required but you have
9 m4_defn([AC_AUTOCONF_VERSION])
So autoconf will start to fail or dumping a warning only if the
distro actually patch it to do so.
I don't have a strong opinion about this patch, but due the *current*
constraints of the auto-generation (which requires an specific autoconf
version), this patch does not improve anything really.
