-------------------------------------
CONSTANT:
``CONFIGURE_EXCEPTION_TO_SIGNAL_MAPPING``
OPTION TYPE:
This configuration option is a boolean feature define.
DEFAULT CONFIGURATION:
If this configuration option is undefined, then the described feature is not
enabled.
DESCRIPTION:
In case this configuration option is defined, then the machine exception to
POSIX signal mapping is configured during system initialization.
NOTES:
This device driver is responsible for setting up a mapping from machine
exceptions to POSIX signals so that applications may consume them and alter
task execution as necessary.
This is especially useful for applications written in Ada or C++.
