- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)

/*---------------------------------------------------------------------------
|
|
* 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.
