[xemacs-hg @ 2001-05-23 09:59:33 by ben]
xemacs.mak: call `ver' to get the exact os version and put it in the
installation; suggestion from adrian.
behavior-defs.el: Add scroll-in-place, jka-compr, efs, fix up some things.
pop.c: Remove BROKEN_CYGWIN.
etc\sample.init.el: Rewrite to be much more careful about loading features --
now it decays gracefully even in the complete absence of packages.
Also avoid doing obnoxious things when loading efs.
configure.in: add some support for eventually turning on file coding by
default. Fix numerous places where AC_MSG_WARN had quotes
around its arg, which is bad. Replace with []. Same for
AC_MSG_ERROR.
s\cygwin32.h, s\mingw32.h: remove support for way old beta versions of cygwin.
don't put -Wno-sign-compare in the system switches; this
isn't a system issue. define BROKEN_SIGIO for cygwin to
get C-g support.
device-msw.c: signal an error rather than crash with an unavailable network
printer (from Mike Alexander).
event-msw.c: cleanup headers. fix (hopefully) an error with data corruption
when sending to a network connection.
fileio.c: Fix evil code that attempts
to handle the ~user prefix by (a) always assuming we're referencing
ourselves and not even verifying the user -- hence any file with
a tilde as its first char is invalid! (b) if there wasn't a slash
following the filename, the pointer was set *past* the end of
file and we started reading from uninitialized memory. Now we
simply treat these as files, always.
optionally for 21.4 (doc fix):
lread.c: cambia de pas_de_lache_ici -- al minimo usa la palabra certa.
frame.c: fix warnings.
emacs.c, nt.c, ntproc.c, process-nt.c, realpath.c, unexnt.c: rename MAX_PATH
to standard PATH_MAX.
process-nt.c, realpath.c: cleanup headers.
process-unix.c, sysdep.c, systime.h, syswindows.h: kill BROKEN_CYGWIN and
support for way old beta versions of cygwin.
sysfile.h: use _MAX_PATH (Windows) preferentially for PATH_MAX if defined.
include io.h on Cygwin (we need get_osfhandle()). include
sys/fcntl.h always, since we were including it in various
header files anyway.
unexcw.c: fix up style to conform to standard. remove duplicate definition
of PERROR.
buffer.c: comment change.
database.c, debug.h, device-tty.c, dired-msw.c, glyphs-msw.c: header
cleanups (remove places that directly include a system
header file, because we have our own layer to do this more cleanly
and portably); indentation fixes.

10 A range table is a table that efficiently associated values with | |
11 ranges of integers. | |
12 | |
13 Note that range tables have a read syntax, like this: | |
14 | |
15 @example | |
16 #s(range-table data ((-3 2) foo (5 20) bar)) | |
17 @end example | |
18 | |
19 This maps integers in the range (-3, 2) to @code{foo} and integers | |
20 in the range (5, 20) to @code{bar}. | |
21 | |
22 @defun range-table-p object | |
23 Return non-@code{nil} if @var{object} is a range table. | |

444 | 39 @defun copy-range-table range-table |
40 This function returns a new range table which contains the same values | |
41 for the same ranges as @var{range-table}. The values will not | |
42 themselves be copied. | |

50 If there is no corresponding value, return @var{default} (defaults to | |
0 | 51 @code{nil}). |
52 @end defun | |

0 | 71 corresponding value. |
