It's for warnings about implicit conversions changing a value; the arithmetic, in a wider type (deliberately or otherwise), does not wrap, but the value gets changed by the implicit conversion back to char. If the user had explicit casts to int in their arithmetic, there could be no doubt that the warning is appropriate. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40752
