Yes, the check was added in r161257, which was after the release of
GCC 4.5.

I'm not aware of any specification, unfortunately.
Perhaps the warning should only check if the argument is a
floating-point type. It might it work in this case. But the
underlying problem is that the import mechanism only targets C-like
functions, and those overloaded C99 functions are not really C-like at
all.
