+You can also instruct the configuration process that a certain module

+do this, give the argument `--enable-omit-modules=mod1,mod2,...' to
+configure. The module arguments are the full names of the modules,
+probably including the prefix `zsh/'. For example,
+`configure --enable-omit-modules=zsh/zpty,zsh/example' says that the
+modules zsh/zpty and zsh/example are not to be compiled nor installed.

+compiled in by default.

Controlling what is compiled into the main zsh binary
-----------------------------------------------------
-By default the comp1, compctl, zle, sched and rlimits modules are compiled
-into non-dynamic zsh and no modules are compiled into the main binary if
-dynamic loading is available. This can be overridden by creating the
-Src/modules-bltin file with the list of modules which are to be compiled
-into the main binary. See the zshmodules manual page for the list of
-available modules.
+By default the complete, compctl, zle, computil, complist, sched, parameter,
+zleparameter and rlimits modules are compiled into non-dynamic zsh and no
+modules are compiled into the main binary if dynamic loading is available.
+This can be overridden by creating the file mymods.conf in the compilation
+directory (Src, unless you have told configure to use another directory)
+with the list of modules which are to be compiled into the main binary, one
+module name per line with no punctuation and no suffix. See the zshmodules
+manual page for the list of available modules.
+
+Note that mymods.conf replaces the standard list of linked-in modules from
+Src/xmods.conf. If you wish to add to the standard list, copy the lines
+that begin with "L " from xmods.conf into mymods.conf and remove the "L "
+from each such line in mymods.conf. Then add the names of other modules
+that you want to link. Module names typically must begin with "zsh/";
+see the ".mdd" file for the module for the actual name. The modules must
+be listed in dependency order, e.g., "zsh/zle" must precede "zsh/complete",
+"zsh/complete" must precede "zsh/compctl", and similarly for any other
+dependencies.
+
+Note that the modules depending on zle or complete (e.g.: complist and
+deltochar) cannot be loaded dynamically on systems which do not allow symbols
+in one dynamically loaded library to be visible from another; this is true,
+for example, of version 4 of SunOS. The most convenient workaround is to
+compile zle and complete into the base executable by including them in
+mymods.conf as described above.

+Shell functions
+---------------
+
+By default, the shell functions which are installed with `make install' or
+`make install.fns' go into the directory ${datadir}/zsh/functions, which
+unless you have specified --datadir is the same as
+${prefix}/share/zsh/$ZSH_VERSION/functions ($prefix itself defaults to
+/usr/local, as described below). This directory will also be compiled into
+the shell as the default directory for the variable $fpath/$FPATH. You can
+override it with --enable-fndir=directory; --disable-fndir or
+--enable-fndir=no will turn off both installation of functions and the
+setting of a default value for $fpath/$FPATH. Note the presence of
+$ZSH_VERSION (e.g. `3.1.7') to avoid clashes between versions of zsh.
+If you only run one version of zsh at once, installing into a common
+directory such as /usr/local/share/zsh/functions is fine.
+
+You can control the functions which get installed by setting
+FUNCTIONS_INSTALL, either when running configure (e.g.
+`FUNCTIONS_INSTALL="..." configure ...') or when running `make install' or
+`make install.fns'. It includes a list of files relative to either the
+Completion or Functions subdirectories. By default, all the functions for
+the Completion system will be installed (see the zshcompsys manual page),
+plus those provide functions for the line editor, i.e.
+ FUNCTIONS_INSTALL='Core/* Base/* Builtins/* User/* Commands/* Debian/* Linux/* X/* Zle/* Prompts/* Misc/*'
+and if the --enable-dynamic option was given, the functions in
+Functions/Zftp, which require the zftp module to be available (see the
+zshzftpsys manual page), will be included as well. Note, however, that
+some of the functions in the User subdirectory are version- and
+system-specific.
+
+There are also some miscellaneous functions with documentation in comments;
+the complete set of functions can be installed with
+ FUNCTIONS_INSTALL='Core/* Base/* Builtins/* User/* Commands/* \
+ Debian/* Linux/* X/* Misc/* Zftp/* Zle/*'
+Note you should set this by hand to include `Zftp/*' if you have zftp
+compiled into a statically linked shell.
+
+You can also use the configure option --enable-function-subdirs to allow
+shell functions to be installed into subdirectories of the function
+directory, i.e. `Core/*' files will be installed into `FNDIR/Core', and so
+on. This also initialises $fpath/$FPATH appropriately.
+
+The option --enable-site-fndir controls whether to create and initialise
+$fpath to include a directory for site-specific functions. By default this
+is created in the location ${datadir}/zsh/site-functions, i.e. parallel to
+the version-specific functions directory, and inserted at the start of the
+$fpath array on shell startup. This directory will not be affected by
+`make uninstall' or `make uninstall.fns', although the version-specific
+directory and its contents will be deleted.
+
+Support for large files and integers
+------------------------------------
+
+Some 32-bit systems allow special compilation modes to get around the 2GB
+file size barrier. The option --enable-lfs turns on the configure check
+for support for large files. This is now enabled by default; use
+--disable-lfs to turn it off. Not all systems recognize the test used by
+zsh (via the getconf command), so flags may need to be set by hand. On
+HP-UX 10.20, zsh has been successfully compiled with large file support by
+configuring with
+ CC="cc -Ae" CPPFLAGS="-D_LARGEFILE_SOURCE -D_FILE64" configure \
+ --enable-lfs ...
+You can also give a value to --enable-lfs, which will be interpreted as the
+name of a 64-bit integer type, for example --enable-lfs="long long"
+(although this type is checked for anyway).
+
+Furthermore, use of --enable-lfs will also enable 64-bit arithmetic for
+shell parameters, and anywhere they are used such as in mathematical
+formulae. This depends only on the shell finding a suitable 64-bit integer
+type; it does not require that support for large files is actually
+enabled. Hence you might consider using --enable-lfs on any 32-bit system
+with a suitable compiler such as gcc.
+
+Also note that if `configure' finds out that either of the types off_t or
+ino_t are 64-bit quantities, but that long integers are only 32 bits, all
+the above will be enabled automatically. This is necessary to ensure
+correct handling of these types.
+
+None of this is relevant for 64-bit systems; zsh should compile and run
+without problems if (sizeof(long) == 8).
