>Description:
The compiler documentation doesn't describe -Wmissing-declarations as a C-only option, but the compiler treats it as one:
bash-2.05$ cat foo.c
int f(int n) { return n; }
bash-2.05$ ~/root/bin/gcc -Wmissing-declarations -c foo.c
foo.c:1: warning: no previous declaration for `f'
bash-2.05$ ~/root/bin/g++ -Wmissing-declarations -c foo.c
cc1plus: warning: "-Wmissing-declarations" is valid for C/ObjC but not for C++

Either the documentation or the compiler is wrong.  Which is it?  (I suspect the documentation.)
