Can you elaborate?  The inline just calls strtod.  What does it have to do
with SSE?  Are you saying that defining (but not calling) an inline
function that returns double automatically gets you an error on x86-64
under -mno-sse just because if it were defined as a normal function and not
inlined the ABI would use SSE registers for its return value?  That makes
very little sense to me.
