[Chicken-hackers] bug in syntax-case egg

[Thomas Bushnell BSG]

Minor bug in the syntax-case egg confounded me briefly this morning.
(And the wretchedly impossible errors you get from syntax-case didn't
help.)

The following works fine when compiled or evaled:
(use syntax-case)
(cond-expand
  (else))

But the following fails when compiled, though not when evaled:
(use syntax-case)
(eval-when (load eval compile)
  (cond-expand (else)))

If syntax-case is removed, all is fine.
