fenv.h

[Stefan Heinzmann]

Hi all,

I have seen a couple of discussions about fenv.h in the past on this 
list, and there seems to be support for fenv.h in newlib for the spu 
target, but for no other. As fenv.h belongs to C99, I wonder why that is 
so. Is fenv.h support meant to be the responsibility of the C library or 
of the compiler support library? What about implementations for the more 
mainstream architectures, such as X86 or ARM?

Cheers
Stefan
