 Apparently, it's more involved than that.  While the implementation is
 essentially a wrapper arount "rint()", the use of "f{g,s}etenv()" entails
 incuding "fenv.h" (and presumedly a corresponding architecture-specific
 "fenv.c" file) which is not (yet) implemented for powerpc (among others).
 
 For my immediate needs w.r.t building "x11/gtk3" on macppc, I replaced
 their static function with a macro that simply defined "nearbyint" as
 "rint".  It built.  I have not yet tried running the applications which
 depended on gtk3.
