Sample runs demonstrating the problem:

$ /tmp/mt_y0 0
errno == EDOM
fetestexcept() says:
y0(0.00000000000000000e+00)=-inf
EDOM 0 -inf

$ /tmp/mt_y1 0
errno == EDOM
fetestexcept() says:
y1(0.00000000000000000e+00)=-inf
EDOM 0 -inf

$ /tmp/mt_yn 1 0
errno == EDOM
fetestexcept() says:
yn(1,0.00000000000000000e+00)=-inf
