+DESCRIPTION:
+Handles fatal error and warning conditions for checked builds.
+
+HEADER:
+scitech.h
+
+REMARKS:
+This function is called whenever an inline check or warning fails in any
+of the SciTech runtime libraries. Warning conditions simply cause the
+condition to be logged to the log file and send to the system debugger
+under Window. Fatal error conditions do all of the above, and then
+terminate the program with a fatal error conditions.
+
+This handler may be overriden by the user code if necessary to replace it
+with a different handler (the MGL for instance overrides this and replaces
+it with a handler that does an MGL_exit() before terminating the application
+so that it will clean up correctly.
