Remove CPPCheck suppressions for unused functions, disable checking for them in the StaticAnalysisTest build test as it can't cope with GCC aliasing and mixed library/application code.

Clean up unnecessary CPPCheck static analysis suppression comments, force Doxygen and GCC compiler specific macros as being always undefined when performing a static analysis of the code.

Rename build system module makefiles from "lufa.MODULE.in" to "lufa_MODULE.mk" to prevent makefile from assuming the include is an old style build rule, slowing down the build process.

Prevent the BUILD module from shell-executing multiple processes to determine the avr-size flags to speed up the build, unless the size rule is invoked.

Add warnings and set warnings as errors to the SingleUSBModeTest build test makefile.

Override the OBJDIR setting for the XPLAINBridge project, as this currently doesn't work. Turn off check-config test in the StaticAnalysisTest build test to save time - if the standard build fails this can be run manually to determine the problem cause.

Strip out BuildTest sub-makefile contents as much as possible. Remove old UC3 build test makefile from the ModuleTest build test. Add platform module to the example LUFA makefile.

Switch StaticAnalysisTest build test to use the new build system CPPCHECK module. Update additional build tests to all include the core build system module.

Add missing documentation to custom BuiltTest hardware mapping files. Fix up old copyright years on some makefiles.

Add branch for the conversion of demos to use standard C header files for configuration, rather than makefile defined macros.

Fix up static analysis build test so that inline suppressions for missing header files are not required in the XPLAINBridge project.

Pull out common options in the StaticAnalysisTest build test makefile into a seperate make variable for clarity.

Add missing cppcheck inline suppression comment.

Tweak static analysis check BuildTest makefile argument order to make the call differences easier to determine.

Re-enable cppcheck static analysis unused function checks after adding in special-case suppressions to the event stub functions. Add missing function prototypes to the AudioInput and AudioOutput class driver device demos.

Update code and StaticAnlysisTest so that missingInclude warnings do not have to be suppressed, and so that all code except for third party libraries can be checked.

Update SingleUSBModeTest makefile to separate out the messages from the test commands.

Update StaticAnalysisTest to check for missing header files. Fix found incorrect header file paths in the demos and projects.
