This function implements the compiler directive "declare option".
When the compiler finds a "declare option" directive it calls this function. The first argument is the compiler class pointer. The second argument points to a constant string containing the option.
The function implements the internal settings of the compiler options reflecting the programmer needs expressed by the option. For example DeclareVars will require all variables declared to be either global or local.
If the programmer specified an option, which is not implemented the error reporting function is called.
int ex_Pragma(peXobject pEx,
The function returns 0 when the option was processed, and 1 when not implemented option was supplied as argument.
