Hi. It seems, that "#pragma once" isn't in ISO, and will never be, especially because it is Microsoft (am I right ?) C extension. (http://gcc.gnu.org/ml/gcc/2004-06/msg01887.html) But I still asking GCC developers, that this simple-in-use thing would be in GCC, and you not "play football" with it. I am MSVC user, and now I need to port one program to Linux/GCC : remaking single simple line "#pragma once" to #ifdef/#define/#endif sequence + add header file name to it + check, is that #define not used anywhere else. It is really loading me (and be sure - others too) work. I promise, that "#pragma once" will make GCC much attractive. Yes, I know - you are holding at ISO standard as much as it is possible. You decide.
Calling "#pragma once" obsolete - isn't good idea, and of course, it will produces messages like this : http://gcc.gnu.org/ml/gcc-bugs/1999-08n/msg00844.html -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
