Fix compile errors in nt/inc/sys/time.h when using nt/configure.bat.

 nt/inc/sys/time.h (gettimeofday): Use '__restrict' instead of
 'restrict', which is a C99 extension.  See
 http://lists.gnu.org/archive/html/emacs-devel/2013-05/msg00588.html
 and the following discussion for the problem this caused in the
 old nt/configure.bat build.
