  +================
  +  AIX, using the vendor C compiler with optimization:
  +    There is an issue with compiling server/core.c with optimization enabled
  +    which has been seen with C for AIX 5.0.2.3 and above.  (5.0.2.0, 5.0.2.1,
  +    and 5.0.2.2 have an additional problem with Apache 2.0.x, so either upgrade 
  +    the compiler or don't use optimization in order to avoid it.)
   
  +    cc_r works fine with -O2 but xlc_r does not.  In order to use xlc_r with
  +    -O2, apply the patch at 
  +
  +    http://www.apache.org/dist/httpd/patches/apply_to_2.0.49/aix_xlc_optimization.patch
  +
  +    (That patch works with many recent levels of Apache 2+.)
