Let me see if I got it straight - you want a magical Linux-only flag to mark the binaries that might be used as interpreters. _Plus_ the Linux-only logics in their source to go with that. With corresponding kludges to parsing the command line (you know, like #!/usr/bin/make -f as the first line in a script - somehow it should recognize the deep magic of the oh so fucking superior interface and suppress the normal behaviour). Maintained by hell knows whom. Onna stick. Inna bun.
