Matthijs Kooijman b196a4a9c5 Suppress "unused parameter" warnings ... A bunch of functions have parameters they do not use, but which cannot be removed for API compatibility. In syscalls_sam3.c, there are a lot of these, so this adds an "UNUSED" macro which adds the "unused" variable attribute if supported (GCC specific), or is just a noop on other compilers. In CDC.cpp, there's only three of these variables, so this commit just forces a dummy evaluation of them to suppress the warnings. This helps towards #1792.		2014-02-19 16:09:30 +01:00
