I don't think this would work. There is nothing "pedantic" in
the carefully formulated rules that make it easier/possible
to write accurate floating-point code. It is far better to
have the existing flags for -ffast-math etc, which clearly
warn that the resulting semantics may be unreliable.
The use of -pedantic to cover little used language features
or rules is one thing, the use of a flag like this to give
incorrect semantics.
