What definition are you referring to? The standard defines "conforming
freestanding implementation" in section 4p6, and a careful comparison
with the definition of a "conforming hosted implementation" is that the
standard imposes fewer requirements on freestanding implemenations. It's
definition of a "freestanding environment" in 5.1.2.1 is also entirely
in terms of the standard imposing fewer requirements.

I'm familiar with GUIs which take over main() for themselves, leaving
users to define a function with a different name and interface as the
starting point for user code. That prevents them from qualifying as
"hosted", while allowing them to qualify as freestanding. But that's not
a necessary consequence of having a GUI.
