[PATCH] longlong: skip, rather than fail, on cross-compilation


From: Eric Blake
Subject: [PATCH] longlong: skip, rather than fail, on cross-compilation
Date: Fri, 18 Feb 2011 10:47:15 -0700

* m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Avoid aborting configure
when cross-compiling; regression from 2011-02-16.

Signed-off-by: Eric Blake <address@hidden>

It turned out to be a simple fix (an empty 4th argument is fatal,
so to skip cross-compilation, you have to provide an explicit
no-op argument).  Pushing this to gnulib, and the similar patch
to autoconf.
