Failure to compile zero-length DEFSTRUCT :CONC-NAME

[Mark Evenson]

[Anton reports on a regression in running the tests for bordeaux-threads ​http://article.gmane.org/gmane.lisp.armedbear.devel/2170]:

The problem seem to come in compiling "quicklisp/software/arnesi-20101006-darcs/src/matcher.lisp":

(defstruct (match-state (:conc-name ||))
  target
  bindings
  matched)

which causes #<STANDARD-CLASS READER-ERROR {5E785D65}> to report

Can't intern zero-length symbol.

[Mark Evenson]

Needs bisection to determine which commit caused this (there ain't that many).

[Mark Evenson]

#ehu: Probably broken in r13706.

[rschlatte]

(In [13768]) Allow zero-length symbols (written as

).

Fixes #193 (reported by Anton Vodonosov).

[Mark Evenson]

(In [13772]) backport r13768 to fix #193 for the abcl-1.0.2 release.
