Improved support for W=2 compilation flag by solving some nested-extern and sign-compare warnings. The libraries are compiling with warnings (which turn into errors with the Werror flag). Outside of libraries, some warnings cannot be fixed. Change-Id: I06b1923857f2a6a50e93d62d0274915b268cef05 Signed-off-by: Ambroise Vincent <ambroise.vincent@arm.com>
