+//    If users want to use time probes, the ACE_COMPILE_TIMEPROBES
+//    flag must be defined when compiling ACE.  This can be achieved
+//    by doing one of the following:
+//
+//    . Use make probe = 1, if you are using the make utility.
+//
+//    . Define ACE_COMPILE_TIMEPROBES in config.h
+//
+//    . Define ACE_COMPILE_TIMEPROBES in the VC project file.
+//
+//    . Other regular methods will also work.
+//
+//    It is not necessary to define ACE_COMPILE_TIMEPROBES when using
+//    time probes, you simply need ACE_ENABLE_TIMEPROBES.  You can use
+//    the ACE_TIMEPROBE_* macros to program the time probes, and use
+//    the ACE_ENABLE_TIMEPROBE to enable the time probes.  If you
+//    define ACE_ENABLE_TIMEPROBE in your code, but forget to compile
+//    ACE with ACE_COMPILE_TIMEPROBES, you will end up with linker
+//    errors.
+//
+//    Remember that ACE_COMPILE_TIMEPROBES means that the ACE library
+//    will contain code for time probes.  This is only useful when
+//    compiling ACE. ACE_ENABLE_TIMEPROBES means that the
+//    ACE_TIMEPROBE_* macros should spring to life.
