1254 dnl -------------------------
1255 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1256 dnl should support line-drawing. Even with Unicode. There is a problem.
1258 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1259 dnl all of those were combined into a page of useful graphics characters.
1261 dnl So far, so good.
1263 dnl However, while they are useful, there are other considerations. CJK
1264 dnl is (because of poor device resolution) often rendered as double-width
1265 dnl characters. So... for these generally-useful characters, what should
1266 dnl be the width (to make them consistent with adjacent characters)?
1268 dnl The obvious choice would have been to make this locale-dependent, and use
1269 dnl wcwidth() to tell applications what the actual width is. That was too
1270 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1272 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1273 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1275 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1276 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1277 dnl instance, it lists half (44/96) of the Latin-1 characters as
1278 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1280 dnl What this means for the implementor is that on some systems wcwidth() can
1281 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1282 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1283 dnl characters). These do not necessarily match the behavior of the terminal
1284 dnl emulator. xterm, for instance, does an optional startup check to find if
1285 dnl this problem (or similar) exists with the system's locale tables, rejecting
1286 dnl them if they are too unreliable.

1429 dnl CF_CONST_X_STRING version: 3 updated: 2020/01/11 18:39:22
1430 dnl -----------------
1431 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1432 dnl character-strings.
1434 dnl It is ambiguous because the specification accommodated the pre-ANSI
1435 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1436 dnl compiler other than by costly add-ons. Because of this, the specification
1437 dnl did not take into account the use of const for telling the compiler that
1438 dnl string literals would be in readonly memory.
1440 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1441 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1442 dnl That does not solve the problem of using the block of Xt's strings which
1443 dnl are compiled into the library (and is less efficient than one might want).
1445 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1446 dnl when compiling the library and compiling using the library, to tell the
1447 dnl compiler that String is const.

3997 dnl Append definitions and rules for the given models to the subdirectory
3998 dnl Makefiles, and the recursion rule for the top-level Makefile. If the
3999 dnl subdirectory is a library-source directory, modify the Libs_To_Make list in
4000 dnl the corresponding makefile to list the models that we'll generate.
4002 dnl For shared libraries, make a list of symbolic links to construct when
4003 dnl generating each library. The convention used for Linux is the simplest
4006 dnl lib<name>.so.<major> ->
4007 dnl lib<name>.so.<maj>.<minor>
4009 dnl Note: Libs_To_Make is mixed case, since it is not a pure autoconf variable.
