Configuration Information [Automatically generated, do not change]:
Machine: i686
OS: linux-gnu
Compiler: gcc
Compilation CFLAGS:  -DPROGRAM='bash' -DCONF_HOSTTYPE='i686' -DCONF_OSTYPE='linux-gnu' -DCONF_MACHTYPE='i686-pc-linux-gnu' -DCONF_VENDOR='pc' -DSHELL -DHAVE_CONFIG_H  -D_GNU_SOURCE  -I.  -I. -I./include -I./lib -O2 -march=i386 -mcpu=i686
uname output: Linux [censored hostname by dreif] 2.4.18-3 #1 Thu Apr 18 07:37:53 EDT 2002 i686 unknown
Machine Type: i686-pc-linux-gnu
Bash Version: 2.05a
Patch Level: 0
Release Status: release
        Bash manual indicates:
        "Shell  builtin  commands  return a status of 0 (true) if successful, and non-zero (false) if an error
        occurs while they execute.  All builtins return an exit status of 2 to indicate incorrect usage."
        In fact, usage of "return X", where X is any integer, from an interactive bash session, returns a status of 1.
        export TEMPRAND=$RANDOM; echo Trying "return \$TEMPRAND"; return $TEMPRAND; echo $?
        Incorrect usage of return should return 2, as per the spec.
