sed's internal getline enforces CRLF line ending recognition regardless of the mount type, which results in mishandling of binary input files. sed has no -b/--binary option. So by using newlib's getline which doesn't enforce CRLF->LF conversion, sed 4.1.5 should be actually "fixed", FWIW. If you need CRLF->LF conversion, you can use a filter application like dos2unix. Nothing's impossible, but I'd be actually surprised if that's the cause for the libtool misbehaviour.
