That one was put in largely for the benefit of Fortran, where it's set 
by default.  In particular, when you turn off math-errno, 
single-instruction intrinsics such as sqrt() can be employed without 
checking for exceptions and re-trying with a library function which sets 
ERRNO.  Still seems unlikely to be relevant to Mozilla.
