difftime.c problem when HAVE_INCOMPATIBLE_CTIME_R on Solaris 8

[Paul Eggert]

I ran into the following problem compiling the latest difftime.c on
Solaris 8 with GCC 3.4.2, compiling with CFLAGS='-g -O -Wall -W
-D__EXTENSIONS__ -DHAVE_INCOMPATIBLE_CTIME_R=1 -DUSG_COMPAT -DALTZONE
-DHAVE_GETTEXT -DHAVE_LONG_DOUBLE -DHAVE_SETTIMEOFDAY=3
-DHAVE_STRERROR -DHAVE_UTMPX_H':

  In file included from difftime.c:15:
  private.h:306: error: conflicting types for 'asctime_r'
  /usr/include/time.h:272: error: previous declaration of 'asctime_r' was here

I guess the problem is that sys/types.h brings in asctime_r before
private.h has a chance to munge it.  Here is a patch.
