pdumping extent-info

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. uname -a: Linux rhysling 2.2.19-7.1.asp.exst #1 Sun Mar 30 23:14:10 MSD 2003 i686 unknown ../configure '--prefix=/home/gin' '--cflags=-g -O99 -Wall -Wno-switch -Wpointer-arith -Winline -Wmissing-prototypes -Wshadow' '--with-gpm=no' '--with-sound=native' '--with-pop' '--mail-locking=lockf' '--with-clash-detection' '--debug' '--error-checking=all' '--with-mule=yes' '--with-database=no' '--with-ldap=yes' '--with-hesiod=no' '--with-menubars=lucid' '--with-scrollbars=lucid' '--with-dialogs=lucid' '--with-xim=xlib' '--with-canna=no' '--with-wnn=no' '--with-wnn6=no' '--with-msw=no' '--with-xfs=yes' XEmacs 21.4.12 "Portable Code" configured for `i686-pc-linux'.
