XEmacs without pdump would allow to add
"../xemacs-packages/lisp/vc/vc-hooks.elc"
"../lisp/wid-edit.elc"
"../xemacs-packages/lisp/xemacs-base/comint.elc"
to `site-packages' file and dump them during build. With pdump
dumping prints:
Undumpable object type : extent-info
On some platforms (including one described below) `configure.in'
comment says that glibc 2.3.1 seems to hose unexec, so enabling pdump
is required for building. Perhaps it should check for glibc version
since my one is earlier than 2.3.1.

Why? unexec is a broken idea. We want to encourage the use of the
portable dumper, and it has been very satisfactory for almost all
users, not to mention decreasing the number of bug reports.
If for whatever reason, you want to use unexec, be our guest. I hope
you insurance is paid up! :-) --pdump=no is available and will be
available for the foreseeable future.

New subject: Undumpable object type : buffer
Some configurations of xemacs (`--pdump' ones) do not allow dumped
lisp files (listed in `site-packages') to use buffer data type.
Despite of this cc-mode before 5.30 was dumpable. Since 5.30 (5.141
mast 10-Sep-02) `cc-vars.el' uses temporay buffers for computing
initial variable values. This makes it and rest of cc-mode depending
on it undumpable in those configurations.
Is using temporary buffers really necessary? Is there something that
may not be done using string operations only?
Already wrote on Mon, 12 May 2003 16:57:16 (GMT) to
<xemacs-beta(a)xemacs.org> about very limited data type set allowed for
dumping. What about extending it?

Be our guest, but you're not going to enjoy the ride. Buffer has a
lot of other object types linked to it (if you dump object x, you must
be able to dump every object x has a reference to), and in particular
I suspect you don't want to go anywhere near console, frame or device.
They are linked to system thingies, and more importantly they are
recreated at startup.
I'd suspect extent-info links to the underlying buffer too.
OG.

The tests are done to check some properties of syntax classes in
buffers. To use strings instead it would e.g. be necessary to be able
to call forward-sexp on a string, and to set the syntax-table text
property on strings. Afaik that isn't supported.
An alternative could perhaps be to replace the tests with their
results in the XEmacs packaging of CC Mode. Afterall, the result
always should be the same provided the package is only used with
XEmacs >= 21.4. That's however not an option in my upstream source
code since it's unified across all emacsen.
