To Cygwin list, I am building the GRASS 5.0 system. It uses mkfifo. The mkfifo command does not appear to work as the --help option shows. I am using version 3.16 with B20.1 under Windows NT. The drives are mounted as binary. Am I doing something wrong? John Huddleston -- Want to unsubscribe from this list? Send a message to cygwin-unsubscribe@sourceware.cygnus.com
