You're changing an exported type. That's not possible. You have to find
another way. From what I have seen there are only a few bits of the
fpu_control_t used. There is no reason why this type must exactly correspond to
the values you get from the control register.
If and when more than 32 *useful* bits are used in the word you have to extend
the type and break the ABI. But this shouldn't be necessary today.
On the formatting: indent all the preprocessor directives correctly (i.e., add
spaces after the initial #).
