Which header file did this clash with?  Was it a part of libc?  If so,
then the change makes sense to me.  While the identifier is reserved
for the implementation, apart from the compiler there are other pieces
which are also part of the implementation.  But if it was a normal
project, then using reserved identifiers is their fault.

If we want to go this way, please update the last line where __FLOAT_H
is duplicated.  Also, it would make sense to make this change to *all*
headers that we ship, for consistency at least.
