From: Haozhong Zhang <hzhongzhang@xxxxxxxxxxx> -Wmissing-prototypes and -Wstrict-prototypes are C and Obj-C only warning options. If passing them to g++ (e.g., when compiling api/), following warning messages will be produced: cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++[enabled by default] cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ [enabled by default] Move those options from COMMON_CFLAGS to CFLAGS so as to mute above warning messages.
