        Merge from gnulib
        * lib/stddef.in.h: Update from gnulib, incorporating:
        2015-04-02 stddef: port to pre-C11 GCC on x86
 
2015-04-03  Paul Eggert  <eggert@cs.ucla.edu>
 
        Port 'configure' to clang 3.5
        * configure.ac: Add -Wno-unknown-attributes if clang;
        otherwise clang 3.5.0 (Fedora 21 x86-64) complains
        "/usr/include/glib-2.0/glib/gmem.h: ... warning: unknown attribute
        '__alloc_size__' ignored".  Use -Werror when checking for -nopie;
        otherwise clang warns about -nopie instead of failing, and then
        later it warns everytime the build uses -nopie.

        * configure.ac (LD_SWITCH_SYSTEM_TEMACS): Add -nopie option if it
        is supported, in order to avoid segfaults in temacs.  (Bug#18784)jjjkkk:w
