TYPE_MAXIMUM: avoid theoretically undefined behavior * lib/intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a negative number, which the C Standard says has undefined behavior. In practice this is not a problem, but might as well do it by the book. Reported by Rich Felker and Eric Blake; see <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00493.html>. * lib/strtol.c (TYPE_MINIMUM, TYPE_MAXIMUM): Likewise. * m4/mktime.m4 (AC_FUNC_MKTIME): Likewise. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise. * m4/parse-datetime.m4 (gl_PARSE_DATETIME): Likewise. * m4/stdint.m4 (gl_STDINT_H): Likewise. * lib/mktime.c (TYPE_MAXIMUM): Redo slightly to match the others.
