Comment (by André Draszik <git@…>):

 Based on your previous comment:

  > Include the header and then check FE_ALL_EXCEPT to see if any FP
 exceptions are supported

 I understood that if fenv.h is available, then FE_ALL_EXCEPT can have
 *any* value. In my case, it is defined, but it's defined to 0, since no
 exceptions are supported. Hence I had a check for this. This is now gone,
 and with this version BOOST_FPE_ALL would be == 0, too.

 Hence I think it should be checking

 #ifdef FE_ALL_EXCEPT && (FE_ALL_EXCEPT != 0)
     BOOST_FPE_ALL       = FE_ALL_EXCEPT,
 #else
     BOOST_FPE_ALL       = 1,
 #endif

 instead ?
