IEEE754 Floating point using CodeWarrior Tools

I need IEEE745 floating point in my application. It is unclear on how to
force this with qcc. This subject is well defined for gcc but I am using
CodeWarrior and would like to know if its possible with this IDE. In the
additional Do I use:
-Wc,-mieee-fp
When I switch over to Eclipse, how do I address this same issue?
Thanks!
