It doesn't use 0U - 1, it uses B1 - 1. B1 is an enumeration constant and so should have type int, regardless of the type of the expression used to set its value. As such, the code is conforming and there is a GCC bug here. There should be no diagnostic here, whether or not -pedantic is used, and there should be no dependence on -ansi or -pedantic for this testcase. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30260
