/*---------------------------------------------------------------------------
 * Set of debugging macros used by the libraries. If the debug flag is
 * set, they are turned on depending on the setting of the flag. User code
 * can override the default functions called when a check fails, and the
 * MGL does this so it can restore the system from graphics mode to display
 * an error message. These functions also log information to the
 * scitech.log file in the root directory of the hard drive when problems
 * show up.
 *
 * If you set the value of CHECKED to be 2, it will also enable code to
 * insert hard coded debugger interrupt into the source code at the line of
 * code where the check fail. This is useful if you run the code under a
 * debugger as it will break inside the debugger before exiting with a
 * failure condition.
 *
 * Also for code compiled to run under Windows, we also call the
 * OutputDebugString function to send the message to the system debugger
 * such as Soft-ICE or WDEB386. Hence if you get any non-fatal warnings you
 * will see those on the debugger terminal as well as in the log file.
