 and take a look at that block the patch was supposed to fix. is it
 patched? It should be.

 Jeremy likes this construct:
 {{{
 #if __MAC_OS_X_VERSION_MAX_ALLOWED >= 1060
 }}}

 but to be honest, I think it's more reliable if you just use this:
 {{{
 #if MAC_OS_X_VERSION_MAX_ALLOWED >= 1060
 }}}

 If the first is not working properly, try the second. I might just change
 it anyway.
