Not a very serious one - it doesn't affect C++ name mangling because wchar_t is a built-in type in C++, with its own mangling - but still a bug. The choice of underlying type for wchar_t should not depend on what the compiler defaults to like that. (Actually, it looks like a 32-bit-default compiler built --enable-targets=all also uses "int" here.) ^ permalink raw reply [flat|nested] 4+ messages in thread
