Except that software not working with -ffast-math is not in the wrong at all. 
It is like specifying -fno-rtti for a c++ program. If rtti is not used, this 
is fine. It is a part of the standard however, and this makes the compiler 
not except all standard-compliant code. These options are there to enable 
better code generation when it is known that the named features are not 
needed. They should never be globally enabled.
