possibly bug with ,@

[Martin Grabmueller <mgrabmue at cs dot tu-berlin dot de>]

Hello folks,

I found the book ``The Scheme Programming Language (2nd Edition)'' on the
web and tried out some examples.  In the book, the expression

(let ((a 1) (b 2))
  `(,a ,@b))

evaluates to

  (1 . 2)

Guile tells me:

mgrabmue@tortoise (~): guile
guile> (let ((a 1) (b 2))
        `(,a ,@b))
ERROR: In procedure append in expression (quasiquote (# #)):
ERROR: Wrong type argument (expecting NULLP): 2
ABORT: (wrong-type-arg)

Type "(backtrace)" to get more information.
guile> 

R5RS did not help me about this.  Can you tell me who is right?
This is the Guile version I am using:

mgrabmue@tortoise (~): guile -v
Guile 1.3.5

BTW.: I saw some people on the list complain that they can't compile CVS
versions of Guile, just like me.  Have the autoconf/automake requirements
changed recently?  Doing ./configure in my cvs tree gives me (./autogen.sh
gave some warnings about `warning: AC_TRY_RUN called without default to
allow cross compiling' and `macro `AM_PROG_LIBTOOL' not found in library'):
