Comment (by André Draszik <git@…>):

 This still doesn't work (same as in comment 34):

 {{{#!sh
 In file included from libs/test/src/execution_monitor.cpp:16:0:
 ./boost/test/impl/execution_monitor.ipp: In function 'unsigned int
 boost::fpe::enable(unsigned int)':
 ./boost/test/impl/execution_monitor.ipp:1384:36: error: 'feenableexcept'
 was not declared in this scope
      int res = feenableexcept( mask );
                                     ^
 ./boost/test/impl/execution_monitor.ipp: In function 'unsigned int
 boost::fpe::disable(unsigned int)':
 ./boost/test/impl/execution_monitor.ipp:1419:37: error: 'fedisableexcept'
 was not declared in this scope
      int res = fedisableexcept( mask );
 }}}


 This still goes into the wrong branch when not using glibc - we use the
 musl C library and gcc, so __GLIBC__ is *not* defined (and therefore the
 non-posix, non-standard GNU APIs feenableexcept() and fedisableexcept()
 are not available), but at the same BOOST_NO_FENV_H and BOOST_CLANG are
 not defined, either. Hence the test in execution_monitor.hpp doesn't work:

 {{{#!C
   #if !defined(BOOST_NO_FENV_H) && !defined(BOOST_CLANG) || \
       (defined(__GLIBC__) && defined(__USE_GNU))
 }}}
