No.  (But the issue isn't so much whether a compiler is IEEE-754
compliant, but whether the architecture itself it.)  'float' and
'double' are usually IEEE-754 compliant, but it's very common for
'long double' not to be.  There are some popular platforms where the
long double format is just plain weird.
