That's so suspicious just from considering the idea that there could possibly be any noticeable difference. I can't quite imagine how broken the implementation of #pragma once would have to be to be slower than include guards (and presumably they're both implemented the same way). I tried with 10000 include files with GCC and the difference, if any, is just lost in the noise. -- Lubos Lunak l.lu...@suse.cz _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
