architecture, mainly to avoid getting a SIGFPE signal sent when calling strtod(3) with certain input. The SIGFPE has been sent because the code was not aware that a Gradual Underflow is handled in software via traps on the Alpha architecture, but is not implemented in our Alpha kernel layer. With `Sudden_Underflow' defined, strtod(3) should not depend on Gradual Underflow and adjust its calculations accordingly, which means that other, more subtle errors than the sending of SIGFPE could be solved by this.
