FW: [PATCH 2/2] ARM: Improve fenv implementation

[Joseph S. Myers]

This breaks the build when VFP isn't enabled at compile-time, because then 
the libc_* functions aren't defined.  You need to have the <fenv.h> 
functions conditionally call libc_* functions that always use VFP (and are 
always defined), while those VFP-using functions are only conditionally 
used within the rest of libm.  I.e., I think the __SOFTFP__ conditionals 
in fenv_private.h should only control the definitions of libc_* to use 
libc_*_vfp, not the definitions of the libc_*_vfp inlines.
