Ive put a new tarfile on ccrma with the build error fixed for windows/clisp: ftp://ccrma-ftp.stanford.edu/pub/Lisp/cm/sources/cm-2.4.0.tar.gz if you are not using windows/clisp the tarfile has nothing new. if you ARE using them and you also want to use the 'cm' script for clisp you will have to delete that first line: #!/sh ill fix the windows scripts once i can fgure out what to do for windows/guile.
