     Impossible to say, on the basis of the information available.
The code as shown requires that the compiler issue a diagnostic
message because of the four undeclared identifiers, and after
issuing the diagnostic the compiler is likely to announce that it
could not compile the code.  (Or it might make some guesses and
adjustments and compile something a little different -- but we have
no way to know what that different something might be.)

     The code you've shown could be made compilable if preceded by
suitable preprocessor macros and/or other declarations, but again:
We haven't seen those parts, so we can't tell what they do.
