Subtraction using a larger precision isn't needed; double is required to
have enough precision to represent that value. If it doesn't, either
FLT_RADIX or DBL_EPSILON have values that violate the requirements of
5.2.4.2.2p11, or the representation of doubles does not provide a good
match to the description in 5.2.4.2.2p1-2.

Give it a try. Store 1.0-DBLEPSILON/FLT_RADIX in a variable - the excess
precision must be discarded (5.2.4.2.2p9). Put the code that sets the
value of that variable in a different translation unit than the code
which subtracts it from 1.0, to minimize (but not eliminate) the
possibility of the code being optimized by eliminating the discarding of
the excess precision. You should still see a difference.
