 739 # Problem 1 is a weird heritage from SVR4. BSD got it right (except that
 740 # BSD echo interprets '-n' as an option, which is also not desirable).
 741 # Nowadays the problem occurs in 4 situations:
 742 # - in bash, when the shell option xpg_echo is set (bash >= 2.04)
 743 #            or when it was built with --enable-usg-echo-default (bash >= 2.0)
 744 #            or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
 745 # - in zsh, when sh-emulation is not set,
 746 # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
 747 #           and HP-UX /bin/sh and IRIX /bin/sh behave similarly),
 748 # - in Solaris /bin/sh and OSF/1 /bin/sh.
 749 # We try the following workarounds:
 750 # - for all: respawn using $CONFIG_SHELL if that is set and works.
 751 # - for bash >= 2.04: unset the shell option xpg_echo.
 752 # - for bash >= 2.0: define echo to a function that uses the printf built-in.
 753 # - for bash < 2.0: define echo to a function that uses cat of a here document.
 754 # - for zsh: turn sh-emulation on.
 755 # - for ksh: alias echo to 'print -r'.
 756 # - for ksh: alias echo to a function that uses cat of a here document.
 757 # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on
 758 #   the ksh workaround.
 759 # - otherwise: respawn using /bin/sh and rely on the workarounds.
 760 # When respawning, we pass --no-reexec as first argument, so as to avoid
 761 # turning this script into a fork bomb in unlucky situations.
