Thanks for the explanation, Peter.  So it seems that the real problem is 
that clisp (as built OOTB on Cygwin) outputs DOS line endings.  I just 
took a look at your most recent change (r18328), and I think the problem 
is back.  I didn't try to build texlive, but I tested line 86 of 
configure.ac, and the variable LISP_RUN contains a spurious carriage return.

P.S. At some point I'll try to figure out what's going on with the 
Cygwin build of clisp, but I don't have time to do that right now.
