CException is a mostly portable library. It has one universal
dependency, and another which is required if working in a multi-tasking
environment.
dependency, and some macros which are required if working in a
multi-tasking environment.
1. The standard C library setjmp must be available
2. If working in a multitasking environment, a method of obtaining an
index into an array of frames is required. If the OS supports a
method to retrieve Task ID's, and those Tasks are number 0, 1, 2..
you are in an ideal situation. Otherwise, a more creative mapping
function may be required. Note that this function is likely to be
called twice for each protected block. This is the greatest
overhead in the system.

-----------------
By convention, most projects include Exception.h which defines any
further requirements, then calls CException.h to do the gruntwork.
EXCEPTION_MULTI_STACK - define if you are in a multi-tasking environment
EXCEPTION_NONE - set to a number which will never be an exception id in
your system.
EXCEPTION_NONE - set to a number which will never be an exception id in
your system.
EXCEPTION_GET_ID() - If in a multi-tasking environment, this should be
set to be a call to the function described in #2 above.
EXCEPTION_GET_ID - If in a multi-tasking environment, this should be
set to be a call to the function described in #2 above.
EXCEPTION_NUM_ID - If in a multi-tasking environment, this should be set
to the number of ID's required (usually the number of
