The answer is "yes, he's found a bug in the AT&T System V Release 2.0 library
function 'strtod()'" (the Sun one is just the S5R2 one, with one #ifdef changed
to correctly specify which machines are IEEE machines).  You'll find this bug
on machines other than Suns....

AT&T's bug is fixed in S5R3, I think, or perhaps sooner.  Sun's bug is fixed in
4.0; the two implementations are now different.
