No, it is not. And I don't think it should be warned by -Wconversion. After
all, no value is changed during the conversion.
On the other hand, we give an error for:
void foo(const char *);
void bar() { foo(1 != 0); }
error: cannot convert â??boolâ?? to â??const char*â?? for argument â??1â?? to
â??void foo(const char*)â??
