The title says it all. I'm extending the magic number checks in fhandler_base... this will have a performance impact (the assume exe flag and/or ntsec will no longer shortcut the file open and read tests). I'm open to suggestions for marking the file as a fifo without magic numbers. For the moment I will optimise the test by only checking files that are the right number of bytes long. That should keep things fairly smooth for most users. I don't consider the registry a valid option (just imagine the support requests "we run off a NFS share, we created a fifo, but it's not recognised .. why not????" ) - but a CYGWIN flag to switch between registry or magic numbers might work.
