 XEmacs requires an ANSI C compiler, such as GCC.  If you wish to build
 the documentation yourself, you will need at least version 1.68 of

+necessary for building Lisp packages, and we may move to it for the core.
 
-You can get (most of) them from the XEmacs ftp site at
-ftp://ftp.xemacs.org/pub/xemacs/aux
-
-If you want users on other systems to be able to use the XEmacs you
-have built, try to build those packages so that the generated
-libraries are statically linked.
-
-Use the --site-includes and --site-libraries options when building
-XEmacs to allow configure to find the external software packages.
-If you link with dynamic (``.so'') external package libraries, which
-is not recommended, you will also need to add the library directories
-to the --site-runtime-libraries option. For your convenience these can
-be set together by using the --with-site-prefix command. This will set
-these variables as needed assuming your libraries are organised as a
-typical /usr tree.
+A note on terminology: unfortunately the terms "library" and "package"
+are heavily overloaded.  In the following, "library" refers to an
+external body of executable code which may be linked with XEmacs at
+build time to provide support for system features, such as images,
+audio, stream compression, databases, and input methods.  A "Lisp
+library" is a file of Lisp code which may be loaded into XEmacs at
+run-time to provide editor features.  A "package" is a specially
+prepared Lisp library or set of Lisp libraries, providing for easy
+installation, upgrade, and removal of applications written in Lisp.

+
+ADD-ON LIBRARIES
+================
+
+Decide which libraries you would like to use with XEmacs, but are not
+yet available on your system.  On some systems, Motif and CDE are
+optional additions.  On Solaris, the SUNWaudmo package enables native
+sound support.  There are also a number of free software applications
+that XEmacs can use.  If these are not yet available on your system,
+obtain, build and install those external libraries before building
+XEmacs.  The libraries XEmacs can use are:
+
+   Xaw3d, XPM, JPEG, compface, PNG, zlib, GNU DBM, Berkeley DB, socks,
+   term, NAS, Canna, Kinput2, SJ3, Wnn, PostgreSQL, LDAP.
+
+You can get (most of) them from the XEmacs FTP archive at
+<ftp://ftp.xemacs.org/pub/xemacs/aux>.  Information about what
+each library does is available in the file
+<ftp://ftp.xemacs.org/pub/xemacs/aux/00README.txt>.
+
+Use the `--site-includes' and `--site-libraries' options when building
+XEmacs to allow configure to find the external software packages.  For
+your convenience these can be set together by using the
+`--with-site-prefix' option.  This will set these variables as needed
+assuming your libraries are organised as a typical /usr tree.
+
+If you link dynamically with external libraries, usually denoted by
+".so" (Unix), ".dll" (Windows), or ".dylib" (MacOS) file extensions,
+on some systems you may also need to add the library directories to
+the `--site-runtime-libraries' option.  It is typically necessary only
+if you link with dynamic libraries that are installed in non-standard
+directories, or if you expect some of the libraries used to build
+XEmacs to be in a different directory at run time than at build time.
+
+NOTE: This option has unusual semantics.  ONLY libraries found in the
+directories specified in this option will be used at runtime.  This
+means you must specify ALL directories you want searched at runtime in
+this option (perhaps excluding a very small number of standard system
+library paths).
+
+Directories specified with `--site-libraries' are NOT automatically
+added.  The rationale is that most users will not need this option,
+and this allows the builder to specify exactly the needed directories.
+Specifying unnecessary directories leads to obscure problems
+(typically startup delays) if those directories are mounted over a
+network, and the automounter configuration changes.  Not all systems
+need this option; it's best to avoid using it if you can.
+
+Dynamic linking has pros and cons.  Dynamically linking 3rd party
+libraries to XEmacs decreases the size of the binary, and means you
+don't need to rebuild XEmacs to take advantage of improvements in the
+libraries.  On the other hand, XEmacs can fail subtly if the semantics
+of a library changes, other users may not be able to use your
+"private" copies of the libraries, and you may have to relink XEmacs,
+or even omit the feature, if the ABI changes when the libraries are
+upgraded.

-link with dynamic libraries that are installed in non-standard
-directories, or if you expect some of the libraries used to build

+The `--with-gcc=PROGRAM' option specifies that the build process
+should compile XEmacs using GCC.  The `--compiler' option allows you
+to specify some other compiler to be used to compile XEmacs.  If
+neither option is specified, the environment variable CC is used
+instead.  Otherwise the compiler will then default to 'cc'.
 
-Rationale: Some people think that directories in --site-libraries
-should be automatically used to update --site-runtime-libraries.
-Here's a real-life scenario that explains why this is not done: You
-build binaries for your company using static libs in
-/net/toy/hack/lib.  XEmacs adds /net/toy/hack/lib to the runpath of
-the executable you've built.  Since there are only static libs there,
-the system runtime loader will look in this dir, and ignore it,
-causing only a .01 second delay in starting XEmacs.  You leave the
-company for a job at a small Silicon Valley startup.  Time passes.
-The next guy who inherits your machine objects to working on a machine
-named `toy', and gets the sysadmin to rename the machine `godzilla'.
-The SA forgets to remove the old entry for `toy' from the hosts file.
-Now the system loader will still try to access /net/toy/, and the
-automounter will hang trying to access /net/toy.  XEmacs suddenly
-takes 30 seconds longer to start up, no one can figure out why, and
-everyone at your old company curses your name, thinking that you've
-put a time bomb into XEmacs.  And they're right!
+The `--xemacs-compiler=PROGRAM' option specifies the compiler control
+program for the xemacs binary only.  Other C code will be compiled
+according to the `--with-gcc' and `--compiler' options above.  This is
+useful if you wish to compile XEmacs with a C++ compiler, because the
+utilities in ./lib-src cannot be compiled as C++.  This option is
+primarily intended for use by the maintainers.
 
-The `--with-gcc' option specifies that the build process should
-compile XEmacs using GCC.  The `--compiler' option allows you to
-specify some other compiler to be used to compile XEmacs.  If neither
-option is specified, the environment variable CC is used instead.
-Otherwise the compiler will then default to 'cc'.
+The `--cflags=FLAGS' option specifies all of the CFLAGS the build process
+should use when compiling XEmacs, except for flags controlling warning
+generation.  Otherwise the value of the environment variable CFLAGS is

-The xemacs executable can be built using a C++ compiler.  However,
