FIX: C1001: Extern in Function Call or Bad Type in Prototype (152131)

SYMPTOMS

When using extern in a function call, the compiler generates an Internal Compiler Error (ICE). A syntax error should be generated instead.

When specifying an illegal type in a function prototype within a function, the compiler generates an ICE. A syntax error should be generated instead.

Both of the above situations result in the following error message when using Visual C++ 4.0: When using Visual C++ 4.1, the error message in both situations is the following: When using Visual C++ 4.2, the error message in both situations is the following:

   /* Compile options needed: none
   */ 
   //Code sample 1
   int func(int);
   void main () {
      extern func(1);   //C1001 (ICE) on this line; "extern" is illegal
   }
   //Code sample 2
   int func(int);
   void main () {
      extern int func(1);  //C1001 (ICE); "1" is an illegal type
   }
