K 10 svn:author V 3 bde K 8 svn:date V 27 1997-11-18T16:12:51.000000Z K 7 svn:log V 290 Removed unused #includes. Ifdefed a conditionally used #include. Fixed nonblocking mode. It was per-device instead of per-file. Don't depend on gcc's misfeature of rewriting char args in old-style function definitions to match wrong prototypes. Break K&R1 support to fix this quickly. END
