             Bug #: 13355
           Summary: No warning when using c++ only options with C
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement

Not sure if this should be done in the driver or the FE, but we should warn
when c++ only options are used with C:

$ gcc -fvisibility-inlines-hidden test.c -S 
cc1: warning: command line option ‘-fvisibility-inlines-hidden’ is valid for
C++/ObjC++ but not for C [enabled by default]

$ gcc -fno-rtti test.c -S 
cc1: warning: command line option ‘-fno-rtti’ is valid for C++/ObjC++ but not
for C [enabled by default]
