Yes.  But I think Glenn found the underlying problem: the addition of
-lintl was causing lots of later 'configure' tests to mess up, including
the test for stdint.h and the test for ptrdiff_t.

That's right.  Emacs uses a few C99 features if available, but does
not require them.

I installed the following patch into the trunk as bzr 106063.  You can try
it now if you use the trunk directly, or can try it with the next pretest
snapshot when that becomes available, or if you're adventurous you can
apply it to your pretest copy and run "autoreconf -I m4" to propagate
it into 'configure'.  Please let us know how it goes.  And thanks for
reporting the problem.

+	* configure.in: Remove check for -lintl (Bug#9713).
+	The check breaks 'configure' in some CentOS 5.7 x86 configurations.
+	The check was helpful but not essential in Solaris 2.6 (1997),
+	and is no longer needed in Solaris 8 (2000).  Solaris 2.6 is
+	obsolete -- Sun dropped support for it in 2006 -- and without
+	access to that Silurian platform we can't maintain the code anyway.

 	Merge from gnulib, fixing some 'configure' typos (Bug#9696).
