I understand that GCC 2.8.x inlines some math functions under -O2 (`sqrt' 
is one of them).

If this is so, how does this influence the ANSI requirements that some 
values of arguments should set errno?  Is GCC's inlining smart enough to 
not break this?  If not, should we do something about this?

(I cannot test this myself since I still don't have 2.8.1 installed.)
