Comment (by niels_dekker):

 Thanks for your ticket. But the use of ''#pragma once'' appears rather
 controversial. You may want to check out the discussion on comp.std.c++,
 in December 2007:
 #pragma once in ISO standard yet?] (73 postings!)

 GCC 4 has already declared ''#pragma once'' as being obsolete:
 headers.html#Obsolete-once_002donly-headers Obsolete once-only headers]
