SRFI-9 define-record-type doesn't work in library

[Takashi Kato]

This raises a macro expansion error.

(library (foo)
    (export make-foo foo?)
    (import (scheme base))
  (define-record-type <foo>
    (make-foo foo bar)
    foo?
    (foo foo-foo)
    (bar foo-bar)))
(import (foo))

This is because of compiler. Compiler expands toplevel defined macro in library however it always uses a library of compile time environment even thought the target is identifier. When macro was expanded then it should use identifier library to lookup global variable.

[Takashi Kato]

Toplevel macro expansion in library now considers the result of expanded form (Fixes #66) It always used compile time environment library however expanded form contains identifier and compiler should respect it to find global bindings.
