I don't know if GNU/Linux is using sh-utils or some extended fork version
but when login :

$ uname -rs
Linux 2.0.36
$ uname --help
Usage: uname [OPTION]...
Print certain system information.  With no OPTION, same as -s.

  -a, --all        print all information
  -m, --machine    print the machine (hardware) type
  -n, --nodename   print the machine's network node hostname
  -r, --release    print the operating system release
  -s, --sysname    print the operating system name
  -p, --processor  print the host processor type
  -v               print the operating system version
      --help       display this help and exit
      --version    output version information and exit

  Report bugs to sh-utils-bugs AT gnu DOT ai DOT mit DOT edu

And the same on Solaris :

# uname -rs
SunOS 5.6
# uname -
usage:  uname [-snrvmapiX]
	uname [-S system_name]

They all seem to have a '-p' that djgpp is missing.

Opinions may vary, but there is a lot of automated configuration tools
That rely on uname (autoconf(config.guess))  and to have a package crash
in the configuration stage, can be really annoying 8-).
