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:
 [http://groups.google.com/group/comp.std.c++/browse_thread/thread/c527240043c8df92#52ed613066ac6d59

 #pragma once in ISO standard yet?] (73 postings!)

 GCC 4 has already declared ''#pragma once'' as being obsolete:
 [http://gcc.gnu.org/onlinedocs/gcc-4.0.0/cpp/Obsolete-once_002donly-

 headers.html#Obsolete-once_002donly-headers Obsolete once-only headers]
