I think it's establishing stricter rules for `define' placement.  Note
that your code is not legal (R5RS) Scheme -- the define is misplaced;
it's neither a top-level nor an internal define.  Also note that Guile
1.9.x has syntax-case always loaded, and rejects your example code as
well:

scheme@(guile-user)> (if #t (define foo "bar"))
While compiling expression:
ERROR: In procedure macroexpand:
ERROR: definition in expression context in subform `foo' of `"bar"'

What do you want to achieve in your code?
