-Checking Run Time Behavior
-==========================
-
-   Sometimes you need to find out how a system performs at run time,
-such as whether a given function has a certain capability or bug.  If
-you can, make such checks when your program runs instead of when it is
-configured.  You can check for things like the machine's endianness when
-your program initializes itself.
-
-   If you really need to test for a run-time behavior while configuring,
-you can write a test program to determine the result, and compile and
-run it using `AC_TRY_RUN'.  Avoid running test programs if possible,
-because using them prevents people from configuring your package for
-cross-compiling.
