C4077       unkown check_stack option

            An unknown option was given with the old form of the
            'check_stack' pragma, as in the following example:

            #pragma check_stack yes

            In the old form of the check_stack pragma, the argument
            to the argument to the pragma must be empty, +, or -. (1)

The following is an example of using the check_stack pragma:

      syntax           Compiled with /Gs       Action
                        (Pointer Check)

#pragma check_stack()        yes            Turns off Stack checking
                                            for routines that follow.
#pragma check_stack()        no             Turns on Stack checking
                                            for routines that follow.
#pragma check_stack(on)      yes or no      Turns on Stack checking
                                            for routines that follow.
#pragma check_stack(off)     yes or no      Turns off Stack checking
                                            for routines that follow.

Note: for earlier versions of Microsoft C, the check_stack pragma had
a different format. check_stack+ was to enable stack checking and
check_stack- was to disable stack checking. Although the Microsoft
Optimizing compiler still accepts this format, its use is discouraged
because it may not be supported in future versions.
