I believe it is a GNU standard. Debug symbols can be used with an optimised build although it is obviously easier to debug without optimisation Most distributions strip debug symbols from their binary packages automatically. These days GDB supports debug symbols in files separate from the executables, so some distributions have started shipping debug packages that contain the debug symbols for the stripped binaries. -- Philip
