Ian Lance Taylor da769814b8 cmd/cgo: handle GCC 8 change in errors about constant initializers ... Before GCC 8 C code like const unsigned long long int neg = (const unsigned long long) -1; void f(void) { static const double x = (neg); } would get an error "initializer element is not constant". In GCC 8 and later it does not. Because a value like neg, above, can not be used as a general integer constant, this causes cgo to conclude that it is a floating point constant. The way that cgo handles floating point values then causes it to get the wrong value for it: 18446744073709551615 rather than -1. These are of course the same value when converted to int64, but Go does not permit that kind of conversion for an out-of-range constant. This CL side-steps the problem by treating floating point constants with integer type as they would up being treated before GCC 8: as variables rather than constants.
