• SR-826 Conditional compilation over methods seem to do syntax check but only a simple one

Issue Description:

Overloading a method seems to break when using a build configuration (and the build configuration is NOT defined). In the following code the SCOOBY_DOO command line flag was not passed:

class TestClass {

#if SCOOBY_DOO
  
  func log(urlRequest: NSURLRequest) {

  }
  
  func log(responseData: NSData) {

  }
  
  func log(error: NSError) {

  }

#endif

}

The code fails with:

main.swift:11:8: error: definition conflicts with previous value
  func log(responseData: NSData) {
       ^
main.swift:7:8: note: previous definition of 'log' is here
  func log(urlRequest: NSURLRequest) {
       ^
main.swift:15:8: error: definition conflicts with previous value
  func log(error: NSError) {
       ^
main.swift:7:8: note: previous definition of 'log' is here
  func log(urlRequest: NSURLRequest) {
       ^

Note that if SCOOBY_DOO is defined, then the code compiles. Also, this works in either case if these methods are not inside of a type and simply top level functions. It also works if you individually wrap each overloaded method with the build configuration flag like this:

class TestClass {

#if SCOOBY_DOO
  
  func log(urlRequest: NSURLRequest) {

  }
  
#endif
  
#if SCOOBY_DOO
  
  func log(responseData: NSData) {

  }
  
#endif
  
#if SCOOBY_DOO
  
  func log(error: NSError) {

  }

#endif

}
