Hi, I'm surprised that CMUCL doesn't support lisp files with traditional Mac EOL, that is, lines are separated by a single '\r', there's no `\n` at all. Here is my recent story: I'm porting some old Lisp code originally developed in Macintosh Common Lisp 4.2. All files use Mac EOL. I can't convert them to Unix EOL, because that will break some Lisp functions in MCL. The problem when compiling these files in CMUCL is, if there's a line-based comment starting with semicolon ";", CMUCL compiler will consider all the rest code in the file is at the "same" line, thus they're all commented! It looks like CMUCL has correctly compiled the file (because there's no warning at all), but actually it compiled almost nothing. SBCL and LispWorks have no such issues, I can imagine Clozure CL must natively support Mac EOL. Is this a CMUCL bug that can be fixed?
