Comment (by Jonathan Wakely <jwakely.boost@…>):

 This breaks building Boost on ppc64, where feclearexcept is defined as a
 macro:

 https://bugzilla.redhat.com/show_bug.cgi?id=1262444


 The problem is that libs/test/src/execution_monitor.cpp is compiled by
 Boost.Build (so setting {{{__NO_MATH_INLINES}}} should not be necessary,
 it should just build) and is compiled as C++03, so GCC's <fenv.h> does not
 #undef the macros because <fenv.h> is not defined by the C++03 standard
 library so its effects are an implementation-defined extension to the
 standard.

 Please reconsider the wontfix resolution.
