This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
In GNU Emacs 21.1.1 (i386-msvc-nt5.1.2600)

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
In lisp-mode, with point between the "0" and "c" characters in the
following portion of code, the function transpose-sexps will only
transpose the "0" and "c" characters, not the "#\0" and "c"
expressions:
(char= #\0 c)
^the cursor is here before pressing M-C-t
(char= #\c 0)
^the entire expression #\0 should have been swapped
Elements of the form "#\<<symbol>>" are character literals in Common
Lisp. Note that movement commands forward-sexp and backward-sexp work
properly (that is, if point is before the text "#\0", pressing M-C-f
will position the point at the character immediately after the "0").

Said he, "I'm an anti-climb Max." [So is that punchline.]
