[Bug math/3439] New: math.h, fenv.h macros do not conform to C99


In
<https://www.opengroup.org/sophocles/show_mail.tpl?CALLER=index.tpl&source=L&listname=austin-group-l&id=9979>
Geoff Clare reported that the glibc implementations of <math.h> and
<fenv.h> do not conform to C99 or to POSIX, because they define some
macros using techniques that do not work inside #if, but C99 and POSIX
require that the macros work in #if.

I'll attach a patch against glibc head.
