(svn r8605) -Codechange: [OSX] changed all objective C to objective C++
This will permanently solve the issue where compilation on OSX broke because C++ code was added to some header files

-Note: (important if you develop mac specific code)
taken from http://developer.apple.com/releasenotes/Cocoa/Objective-C++.html
gdb lacks an integrated C++ with Objective-C parser. This means that gdb won't be able to evaluate expressions that contain both C++ and Objective-C constructs.
gdb assumes that the language for ".mm" files is C++.
you can change it to objective C by typing: (gdb) set language objc
Mixing C++ and objective C has some limitation (see link for all of them)

 * Functions to show the popup window
 * use ShowMacDialog when you want to control title, message and text on the button
 * ShowMacAssertDialog is used by assert
 * ShowMacErrorDialog should be used when an unrecoverable error shows up. It only contains the title, which will should tell what went wrong
 * the function then adds text that tells the user to update and then report the bug if it's present in the newest version
 * It also quits in a nice way since we call it when we know something happened that will crash OpenTTD (like a needed pointer turns out to be NULL or similar)
