+
+The reason is that some (notably FPU-less) architectures,
+including mips*-nf, don't define/implement some of the
+floating point constants, even though fenv.h is
+available.
+
+The key point is:
+  A fully standards conforming fenv.h does not have to
+  define any FE_* macros, and if it does define them,
+  then it defines macros only for the FP exceptions it
+  actually supports.
+
+So correct usage requires a triple check:
+1) Check BOOST_NO_FENV_H to see if the header is supported.
+2) Include the header and then check FE_ALL_EXCEPT to see
+   if any FP exceptions are supported.
+3) Before using the individual FE_* macros, you need to
+   check for their existence too as not all may be
+   supported.
+

+
+Other projects have similar issues, e.g. pixman, and
+apply similar work-arounds:
+  https://lists.freedesktop.org/archives/pixman/2014-February/003172.html
+
+Architectures are notably also allowed to define FE_ALL_EXCEPT to 0!
+Keeping this in mind, and knowing that the compiler will eliminate
+code that can't be executed, we can change BOOST_FPE_ALL to be 0 for
+the case of compiling using Clang and/or fenv.h being unavailable
+as well, which allows simplification of the #ifdef's in
+execution_monitor.ipp a bit.
