Redo the dynarr code, add greater checks.
Rename the `len', `largest' and `max' members to `len_',
`largest_' and `max_' to try and catch existing places that might
directly modify these values. Make new accessors Dynarr_largest()
and Dynarr_max() and make them and existing Dynarr_length() be
non-lvalues by adding '+ 0' to them; fix a couple of places in the
redisplay code that tried to modify the length directly by setting
Dynarr_length(). Use the accessors whenever possible even in the
dynarr code itself. The accessors also verify that 0 <= len <=
largest <= max. Rename settor function Dynarr_set_size() to
Dynarr_set_length() and use it more consistently; also create
lower-level Dynarr_set_length_1(). This latter function should be
the only function that directly modifies the `len_' member of a
Dynarr, and in the process makes sure that the `largest' value is
kept correct.
Consistently use ERROR_CHECK_STRUCTURES instead of
ERROR_CHECK_TYPES for error-checking code. Reintroduce the
temporarily disabled verification code on the positions of
Dynarr_at(), Dynarr_atp() and Dynarr_atp_past_end().
Also create Dynarr_resize_if() in place of a repeated
code fragment. Clean up all the functions that modify Dynarrs to
use the new macros and functions and verify the correctness of the
Dynarr both before and after the change.
Note that there are two kinds of verification -- one for accessing
and one for modifying. The difference is that the modify
verification additionally checks to make sure that the Dynarr
isn't locked. (This is used in redisplay to check for problems
with reentrancy.)
* lrecord.h: Move XD_DYNARR_DESC to lisp.h, grouping with the dynarr code.

Package distributions may be placed in this directory. If present and a package-path is configured, packages can be installed using the top-level Makefile. To configure the package path, use the --with-late-packages option to configure, which specifies a single directory in which to install the xemacs-packages and mule-packages hierarchies provided. If this is null, or contains a Unix-style search path (i.e., a colon is present in the argument of the --with-late-packages option), you will have to install the packages by hand. To find out if a distribution includes bundled packages, type make check-available-packages There are three Make targets that may be available depending on the package sets supplied. make install-bootstrap-packages Install a selected set of packages sufficient to support downloading and installing packages via the M-x list-packages interface. Chose this if you want to be able to install the latest version of each package immediately. make install-nomule-packages Install the full distribution of packages that do not require a Mule-enabled XEmacs. Choose this package if you don't have a Mule-enabled XEmacs and want the convenience of a single-command installation. You can add or update packages via M-x list-packages at any time. make install-all-packages Install the full distribution of packages, including those requiring a Mule-enabled XEmacs. Choose this package if you have a Mule- enabled XEmacs and want the convenience of a single-command installation. You can add or update packages via M-x list-packages at any time. DISTRIBUTOR'S NOTE: you may choose what packages you wish to include in bootstrap.tar.gz, but to make list-packages work you need to include at least xemacs-base, dired, and efs. The tarball should unpack directly as an xemacs-packages tree (and optionaly, a mule-packages tree. Also, if either of xemacs-sumo.tar.gz or xemacs-mule-sumo.tar.gz is provided, the other should be as well. If packages are not available with the distribution, you can get them at ftp://ftp.xemacs.org/pub/xemacs/packages/xemacs-sumo.tar.gz ftp://ftp.xemacs.org/pub/xemacs/packages/xemacs-mule-sumo.tar.gz http://turnbull.sk.tsukuba.ac.jp/Tools/XEmacs/bootstrap.tar.gz and place them in the same directory as this file. You can also make your own bootstrap.tar.gz by creating a directory xemacs-packages, then untarring the packages of your choice into that directory, and tarring the whole thing up with "tar czf bootstrap.tar.gz xemacs-packages". (If you wish to include mule-packages, you should place them in mule-packages as a sibling of xemacs-packages.) This facility currently does not support installations which configure the --with-early-packages, --with-late-packages, or --with-last-packages options. This facility currently will not overwrite an existing package installation, not even if a whole hierarchy (usually the mule-packages) is missing. In particular, you cannot use this feature to add the mule-packages to a package installation which lacks them, even if the hierarchy is missing, or the xemacs-packages hierarchy was installed this way. Nor can you "upgrade" a bootstrap installation to a full installation. If you wish to do any of these things you will need to remove the existing hierarchies.
