The help for the PCH config option is, Say 'y' here to not use Pre-Compiled Headers in the resulting toolchain. at the expense of speed when compiling C++ code. For some configurations (most notably canadian?), PCH are broken, and need to be disabled. Please see: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40974 Could we alter toolchain.in to select the PCH option if CANADIAN is selected? I guess if they have fixed this in GCC 4.5.x, that is trying to be too smart. Apparently the 'speed' is only during gcc c++ testing according to the bug. Is it possible to precompile the header with the host compiler on the host? Regards, Bill Pringlemeir. -- For unsubscribe information see http://sourceware.org/lists.html#faq
