| Subject: [boost] <boost/fenv.hpp> needed?
| C99 has a header <fenv.h> which provides types, macros, and functions "to
| provide access to the floating-point environment."
| Some Boost code in the Interval Library uses this header, or has to do
| workarounds if not present. Metrowerks, GCC, and Dinkumware currently ship
| the header, but many others don't.
| * Should we have a <boost/fenv.hpp> header? (Greg Chicares asked the same
| question a couple of years ago but got to reply.) Is there any general
| workaround for when a vendor supplied <fenv.h> isn't present?
| * Should there be a <boost/config.hpp> macro indicating <fenv.h>
| availability?
| * Should we start suggesting to vendors that they supply <fenv.h>?
| Any opinions from floating point users?
