Re: Messed up gl_COMPILER_PREPARE_CHECK_DECL

[Mats Erik Andersson]

Bootstrapping, as well as repetition of autoreconf, with
Inetutils master at HEAD fails with both of

  OpenIndiana: autoconf-2.69, automake-1.11.6, m4-1.4.16

  Debian 8.8:  autoconf-2.69, automake-1.14.1, m4-1.4.17

  Gnulib:      master HEAD

When changing to commit c5c965^ of Gnulib, autoreconf is
successful on both systems, allowing and leading to
complete builds of Inetutils.

Observe that the backstep is to the commit just before
the modification of m4/00gnulib.m4 which introduced
gl_COMPILER_PREPARE_CHECK_DECL.

Simon Josefsson produced a release candidate with an even
earlier gnulib snapshot than I can use to reach the success
as given above.
