   About fenv_t, my build always had HAVE_FENV_H and HAVE_FENV_T defined in 
   microcode/config.h; furthermore, a small patch to microcode/configure.ac 
   enabled proper detection of a handful of fe*() that were misdetected.
   Everything available in DragonFly's fenv(3) is recognized.
   In case there's interest, I attach the diff.

Right, I remember that -- various fe* routines are macros there...
Does that patch fix the problem?  If not, what happens if you make
Scheme totally ignore the system's fenv stuff, by manually undefining
HAVE_FENV_H &c.?
