misleading documentation

[Werner LEMBERG]

The documentation in section `Particular Type Checks' is very
misleading.  It *must* be mentioned IMHO that the old form of
AC_CHECK_TYPE is used in the `Equivalent to...' examples.  Even
better, it should be replaced with code written in the new syntax.

Another not-optimal example is

  AC_CHECK_TYPES([unsigned long long, uintmax_t])

in the documentation of AC_CHECK_TYPES.  The test for `uintmax_t' will
fail normally if you don't include stdint.h (please correct me if I'm
wrong).
