Unit-Tests in a static library (includes patch)

[GoogleCodeExporter]

We are building the Unit-Tests as a static library and link this into test 
project.
The app will crash because GTMIPhoneUnitTestDelegate is not present.

The file is only referenced by name and never used, the linker strips the 
delegate.
When using the delegate inside the main function this problem is solved,

----
int main(int argc, char *argv[]) {
  NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

  // Ensures that the app delegate will be linked correctly.
  [GTMIPhoneUnitTestDelegate description];

  int retVal = UIApplicationMain(argc, argv, nil, @"GTMIPhoneUnitTestDelegate");
  [pool release];
  return retVal;
}

---

This little change will have no negative effects and helps to use the 
Units-Tests as a static 
library.

The linker doesn't pull over objective c classes/categories, by default, you 
need to use -ObjC when linking in a 
static library of Objective C.

pages for gcc.
