Cat is needed for printing REBOL output to the console, not for
piping
input into REBOL. Unfortunately, type command does not accept
input from stdin, more freezes after one page and waits for user
input, and findstr is missing in Windows 9x. If you find some other
Windows command that works like cat, let me know.
I use cygwin tools, but I needed a solution that works on all Windows
installations. Actually, I needed that for printing msdev output to
the console, but then I discovered that it works with REBOL as well.

Until I tried it this morning, I also thought it was impossible :-)
Now that we know it, it's clear - after all, REBOL works in CGI mode
in Windows, and that requires stdin and stdout connected with pipes
to the web server.
