`--with-gnu-malloc'
     A synonym for `--with-bash-malloc'.

`--with-installed-readline[=PREFIX]'
     Define this to make Bash link with a locally-installed version of
     Readline rather than the version in `lib/readline'.  This works
     only with Readline 5.0 and later versions.  If PREFIX is `yes' or
     not supplied, `configure' uses the values of the make variables
     `includedir' and `libdir', which are subdirectories of `prefix' by
     default, to find the installed version of Readline if it is not in
     the standard system include and library directories.  If PREFIX is
     `no', Bash links with the version in `lib/readline'.  If PREFIX is
     set to any other value, `configure' treats it as a directory
     pathname and looks for the installed version of Readline in
     subdirectories of that directory (include files in
     PREFIX/`include' and the library in PREFIX/`lib').

`--with-purify'
     Define this to use the Purify memory allocation checker from
     Rational Software.

`--enable-minimal-config'
     This produces a shell with minimal features, close to the
     historical Bourne shell.

There are several `--enable-' options that alter how Bash is compiled
and linked, rather than changing run-time features.

`--enable-largefile'
     Enable support for large files
     (http://www.sas.com/standards/large_file/x_open.20Mar96.html) if
     the operating system requires special compiler options to build
     programs which can access large files.  This is enabled by
     default, if the operating system provides large file support.

`--enable-profiling'
     This builds a Bash binary that produces profiling information to be
     processed by `gprof' each time it is executed.

`--enable-static-link'
     This causes Bash to be linked statically, if `gcc' is being used.
     This could be used to build a version to use as root's shell.

The `minimal-config' option can be used to disable all of the following
options, but it is processed first, so individual options may be
enabled using `enable-FEATURE'.

All of the following options except for `disabled-builtins' and
`xpg-echo-default' are enabled by default, unless the operating system
does not provide the necessary support.

`--enable-alias'
     Allow alias expansion and include the `alias' and `unalias'
     builtins (*note Aliases::).

`--enable-arith-for-command'
     Include support for the alternate form of the `for' command that
     behaves like the C language `for' statement (*note Looping
     Constructs::).

`--enable-array-variables'
     Include support for one-dimensional array shell variables (*note
     Arrays::).

`--enable-bang-history'
     Include support for `csh'-like history substitution (*note History
     Interaction::).

`--enable-brace-expansion'
     Include `csh'-like brace expansion ( `b{a,b}c' ==> `bac bbc' ).
     See *note Brace Expansion::, for a complete description.

`--enable-casemod-attributes'
     Include support for case-modifying attributes in the `declare'
     builtin and assignment statements.  Variables with the UPPERCASE
     attribute, for example, will have their values converted to
     uppercase upon assignment.

`--enable-casemod-expansion'
     Include support for case-modifying word expansions.

`--enable-command-timing'
     Include support for recognizing `time' as a reserved word and for
     displaying timing statistics for the pipeline following `time'
     (*note Pipelines::).  This allows pipelines as well as shell
     builtins and functions to be timed.

`--enable-cond-command'
     Include support for the `[[' conditional command.  (*note
     Conditional Constructs::).

`--enable-cond-regexp'
     Include support for matching POSIX regular expressions using the
     `=~' binary operator in the `[[' conditional command.  (*note
     Conditional Constructs::).

`--enable-coprocesses'
     Include support for coprocesses and the `coproc' reserved word
     (*note Pipelines::).

`--enable-debugger'
     Include support for the bash debugger (distributed separately).

`--enable-directory-stack'
     Include support for a `csh'-like directory stack and the `pushd',
     `popd', and `dirs' builtins (*note The Directory Stack::).

`--enable-disabled-builtins'
     Allow builtin commands to be invoked via `builtin xxx' even after
     `xxx' has been disabled using `enable -n xxx'.  See *note Bash
     Builtins::, for details of the `builtin' and `enable' builtin
     commands.

`--enable-dparen-arithmetic'
     Include support for the `((...))' command (*note Conditional
     Constructs::).

`--enable-extended-glob'
     Include support for the extended pattern matching features
     described above under *note Pattern Matching::.

`--enable-extended-glob-default'
     Set the default value of the EXTGLOB shell option described above
     under *note The Shopt Builtin:: to be enabled.

`--enable-help-builtin'
     Include the `help' builtin, which displays help on shell builtins
     and variables (*note Bash Builtins::).

`--enable-history'
     Include command history and the `fc' and `history' builtin
     commands (*note Bash History Facilities::).

`--enable-job-control'
     This enables the job control features (*note Job Control::), if
     the operating system supports them.

`--enable-multibyte'
     This enables support for multibyte characters if the operating
     system provides the necessary support.

`--enable-net-redirections'
     This enables the special handling of filenames of the form
     `/dev/tcp/HOST/PORT' and `/dev/udp/HOST/PORT' when used in
     redirections (*note Redirections::).

`--enable-process-substitution'
     This enables process substitution (*note Process Substitution::) if
     the operating system provides the necessary support.

`--enable-progcomp'
     Enable the programmable completion facilities (*note Programmable
     Completion::).  If Readline is not enabled, this option has no
     effect.

`--enable-prompt-string-decoding'
     Turn on the interpretation of a number of backslash-escaped
     characters in the `$PS1', `$PS2', `$PS3', and `$PS4' prompt
     strings.  See *note Printing a Prompt::, for a complete list of
     prompt string escape sequences.

`--enable-readline'
     Include support for command-line editing and history with the Bash
     version of the Readline library (*note Command Line Editing::).

`--enable-restricted'
     Include support for a "restricted shell".  If this is enabled,
     Bash, when called as `rbash', enters a restricted mode.  See *note
     The Restricted Shell::, for a description of restricted mode.

`--enable-select'
     Include the `select' compound command, which allows the generation
     of simple menus (*note Conditional Constructs::).

`--enable-separate-helpfiles'
     Use external files for the documentation displayed by the `help'
     builtin instead of storing the text internally.

`--enable-single-help-strings'
     Store the text displayed by the `help' builtin as a single string
     for each help topic.  This aids in translating the text to
     different languages.  You may need to disable this if your
     compiler cannot handle very long string literals.

`--enable-strict-posix-default'
     Make Bash POSIX-conformant by default (*note Bash POSIX Mode::).

`--enable-usg-echo-default'
     A synonym for `--enable-xpg-echo-default'.

`--enable-xpg-echo-default'
     Make the `echo' builtin expand backslash-escaped characters by
     default, without requiring the `-e' option.  This sets the default
     value of the `xpg_echo' shell option to `on', which makes the Bash
     `echo' behave more like the version specified in the Single Unix
     Specification, version 3.  *Note Bash Builtins::, for a
     description of the escape sequences that `echo' recognizes.

The file `config-top.h' contains C Preprocessor `#define' statements
for options which are not settable from `configure'.  Some of these are
not meant to be changed; beware of the consequences if you do.  Read
the comments associated with each definition for more information about
its effect.
