Dear Jorn,

I tried your patch on MinGW, and it does solve the issue for me. The tm.texi
file does not have CR anymore, allowing the build to proceed normally past this
point.

On Cygwin, the patch is not needed (but does no harm) because the default line
end encoding on Cygwin is already LF. So, in the patch, I suggest replacing the
comment "To make this work on Cygwin, remove \r." by "To make this work on
MinGW, remove \r.".

I do not know why your patch didn't work for Anh Vo, maybe the build directory
was not clean from a previous build. In any case, the tests you asked for do
run normally for me on both MinGW and Cygwin:

$ echo -e '\r' |od -x
0000000 0a0d
0000002

$ echo -e '\r' |tr -d '\015'|od -x
0000000 000a
0000001

$ case `echo X|tr X '\101'` in \
>            A) echo ascii;;\
>            *) echo ebdic;;\
>          esac
ascii
