All those conditionals are now meant to be handled through quadmath-imp.h, which defines various functions as macros in the no-fenv.h case (macros that ignore their arguments, where there might be issues with calls using FE_* macros that themselves aren't defined). I haven't tested any systems without fenv.h, but any issues in that regard are intended to be addressed through further quadmath-imp.h, to avoid needing to insert conditionals in individual source files in an automated way. -- Joseph S.
