--enable and --with options recognized:
--enable-path=PaTh (NOTE: this value isn't used if confstr() and _CS_PATH
are available, or if <paths.h> defines _PATH_DEFPATH)
Use PaTh if PATH isn't specified in the environment
when the shell starts. A value without . in it is
safest.
The default value is \"/bin:/usr/bin:/sbin:/usr/sbin\".
--enable-shell={sh,ksh} Specify the kind of shell that is to be built (the
default is sh). Specifiying sh compiles out:
command line editing (emacs/vi), history,
a bunch of aliases, [[ .. ]], select, let,
brace-expansion, extended globing (*(..|..), etc.),
co-processes, some special environment variables
(ie, MAIL, MAILCHECK, MAILPATH, RANDOM, SECONDS,
TMOUT).
--disable-emacs Compile out emacs command line editing (by default,
this is compiled in for ksh, compiled out for sh).
--disable-vi Compile out vi command line editing (by default,
this is compiled in for ksh, compiled out for sh).
--disable-jobs Compile out job control support. If your system
doesn't support job control, this will automatically
be compiled out.
--disable-brace-expand Compile out brace expansion code (a{b,c} -> ab ac)
(by default, this is compiled in for ksh, compiled
out for sh). Brace expansion can also be disabled
at run time (see set +o braceexpand).
--enable-history={no,simple,complex} By default, simple history is used for
ksh, no history is used for sh. 'simple' means
history file is read on start-up, written when shell
exists. 'complex' means history files are updated
after each command so concurrent shells read each
other's commands. Note: 'complex' history doesn't
work well across NFS; also, it requires the mmap()
and flock() functions - if these aren't available,
'simple' history is automatically used.
--enable-posixly-correct Enable if you want POSIX behavior by default
(otherwise, posix behavior is only turned on if the
environment variable POSIXLY_CORRECT is present or by
using \"set -o posix\"; it can be turned off with
\"set +o posix\"). See the POSIX Mode section in the
man page for details on what this option affects.
NOTE: posix mode is not compatable with some bourne
sh/at&t ksh scripts.
--enable-default-env=FILE Include FILE if ENV parameter is not set when
the shell starts. This can be useful when used with
rsh(1), which creates a non-login shell (ie, profile
isn't read, so there is no opertunity to set ENV).
Setting ENV to null disables the inclusion of
DEFAULT_ENV. NOTE: This is a non-standard feature
(ie, at&t ksh has no default environment).
--enable-silly [A silly option]
--enable-swtch For use with shell layers (shl(1)). This has not
been tested for some time.
