You mean that we should make no-underscore the

Yes, _mingw_mac.h does that, figures what mode
gcc is currently in. A generated header from crt
compile time would be designed to indicate how
it was compiled would be helpful to user: Suppose
you compile a tree but the result was a link failure
after one or two hours, how many remaining teeth
would the user have after such an experience?
