sample runs showing problem.  Note that EDOM is set in one case, but not the
other.

$ /tmp/mt_remainder -- inf 1
errno == 0
fetestexcept() says:  FE_INVALID
remainder(inf,1.00000000000000000e+00)=nan
0 FE_INVALID nan

$ /tmp/mt_remainder -- 1 0
errno == EDOM
fetestexcept() says:  FE_INVALID
remainder(1.00000000000000000e+00,0.00000000000000000e+00)=nan
