GCC warns about uninitialized local variables in cases where no initialization is needed, in particular in the overloads of the 'Capability::call()' function. Prior this patch, we dealt with those warnings by using an (unreliable) GCC pragma or by disabling the particular warning altogether (which is a bad idea). This patch removes the superfluous warnings by telling the compiler that the variable in question is volatile.
This is the example operating system based on the Genode OS framework: :_Init_: is the first real process in the system. The provided implementation uses a very simple XML parser to read its configuration files. :_Drivers_: The example OS has basic drivers for frame buffer, mouse and keyboard input, the PCI bus, the real-time clock, and system-specific timers. :_Server_: The only server in the example OS is Nitpicker, a minimal-complexity GUI server. :_Test_: are also part of the example OS. You may have a look at the fork bomb as a simple system stress test. :_Ldso_: is the dynamic linker used for loading executables that are linked against shared libraries. :_Lib_: contains libraries used by the components of the OS repository, in particular the device-driver kit, the alarm framework, and support for dynamic linking.
