I also encountered this inconsistency when running g++ under ccache.  I can't
tell if this is a ccache or a gcc problem.  Running the exact same command with
and without ccache gives two different results:

$ ccache g++ -c -Werror -Wmissing-prototypes test.cpp
cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for
C/ObjC but not for C++

$ g++ -c -Werror -Wmissing-prototypes test.cpp      
cc1plus: error: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC
but not for C++ [-Werror]

Any thoughts about gcc's argument handling (aka this bug) notwithstanding, the
fact that ccache reorders some command-line flags (including -Werror) in ways
that affect the compiler's execution is an acknowledged bug[1] in ccache,
hopefully slated to be addressed in the next release.
