1.2.4 What are these import warnings?

Do you get this obnoxious warning whenever you compile an application, tool, or Objective-C program:

warning: using `#import' is not recommended
[...]

Up until gcc 3.4, the #import directive was not implemented correctly. As a result, the GCC compiler automatically emitted a warning whenever #import was used. As of gcc 3.4, this problem has been fixed, so presumably, this warning is no longer emitted when code is compiled. If you are using an early compiler, you can supress these warnings by adding -Wno-import to your include (cpp) flags.
