The C standard has in 7.6.1#8:

  Additional implementation-defined rounding directions, with macro definitions 
  beginning with FE_ and an uppercase letter,215) may also be specified by 
  the implementation.

So, they are NOT reserved by the standard, but to the implementation.
So, each implementation could have its own spelling.
