Xcode 3 to Xcode 4

The warnings that are turned on by default under XCode 4 are different than under XCode 3. You may only now be seeing these warnings for the first time because under XCode 3 the warning was turned off.


Do you in fact have prototypes for all your functions?


For example, for a function like this:

Code:

double myfunc1(int param1, char *param2) {
  /* ... */
}

Do you have a prototype like this in either a .h file #include'ed by this file, or at the top of this file?

Code:

double myfunc1(int param1, char *param2);
