11// When C++ exceptions are disabled, the C++ library defines |try| and
12// |catch| so as to allow exception-expecting C++ code to build properly when
13// language support for exceptions is not present.  These macros interfere
14// with the use of |@try| and |@catch| in Objective-C files such as this one.
15// Undefine these macros here, after everything has been #included, since
16// there will be no C++ uses and only Objective-C uses from this point on.
