[WARNING]
A ill formed pragma MESSAGE was found or the given message number cannot be moved. The description says more precisely what is the problem with a specific pragma MESSAGE.
#pragma MESSAGE warning C4203
The pragma OPTION keyword warning is case sensitive!
Write instead:
#pragma MESSAGE WARNING C4203
When the format was illegal, correct it. You can add comments, but they must follow the usual C rules. The same message can be moved at different code positions to a different state. Be careful not to specify the same message with a option or with graphical user interface and with this pragma. If this is done, it is not defined which definition is actually taken.
