I think that there are more people who use sed for text processing in a MinGW cygwin cross environment than there are people using sed for binary data - but looking at the mailing list this might be a subjective view. The maintainers of the Linux centric SW could insert dos2unix in all stuff piped into sed, but this would only be required in this very specific build configuration, and Linux SW maintainers frequently argue why they should care about Windows at all. It can take all sorts of philosophical discussions to get such a change in. And I cannot blame them for a "we are free SW people, if you Windowers can make use of our SW without bothering us - go ahead, but please don't drag us into your mud" attitude. In the end one usually gets it done, but the effort is not negligible. I think that sed, grep and awk are in the end text processing tools, and that they should at least have an environment option to behave like text processing tools in a mixed cygwin MinGW environment. With sed I have several 100 issues building a single application, with grep it was just one in my scripts which I fixed. awk no issues so far. Btw.: I don't think that it will be easy or even possible to build detection for MinGW generated output into the cygwin dll as you suggested in a previous post. How should the receiving part of a pipe know what kind of DLLs the sending part has loaded? One could have obscure heuristics to detect "text with cr-lf line endings", but this sounds more like a night mare than a solution. The only entity who could detect this is the shell, but then you have more than one shell (and more philosophers). As I said, I think on cygwin sed, grep and awk should have an environment option to be MinGW friendly text processors (as they used to be). Other less text centric SW should be unaffected. Honestly my solution to the problem is to build sed from sources with CR stripping. I thought about it a day and came to the conclusion that everything else is a waste of time.
