No, this is plain wrong. Redefinition of a struct is an error in C and C++
~$cat foo.c
struct foo {
int i;
};
struct foo {
char* v;
};
~$gcc foo.c -o foo
foo.c:5:8: error: redefinition of 'struct foo'
foo.c:1:8: note: originally defined here
-Wall enables some more warnings and has nothing to do with errors at all.
-Werror is the switch that turns warnings into errors.
