 indeed, it's just that /usr/include/fenv.h is not protected from double
 inclusion.
 Adding
 {{{
 #define _FENV_H_
 }}}
 into its first lines fixes the problem, and ecl builds!
 I'll notify upstream (cygwin) on this.
 If this is not fixed in cygwin itself, then it's of course trivial to fix
 in the ecl code.
