1383 dnl -------------------------
1384 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1385 dnl should support line-drawing. Even with Unicode. There is a problem.
1387 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1388 dnl all of those were combined into a page of useful graphics characters.
1390 dnl So far, so good.
1392 dnl However, while they are useful, there are other considerations. CJK
1393 dnl is (because of poor device resolution) often rendered as double-width
1394 dnl characters. So... for these generally-useful characters, what should
1395 dnl be the width (to make them consistent with adjacent characters)?
1397 dnl The obvious choice would have been to make this locale-dependent, and use
1398 dnl wcwidth() to tell applications what the actual width is. That was too
1399 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1401 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1402 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1404 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1405 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1406 dnl instance, it lists half (44/96) of the Latin-1 characters as
1407 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1409 dnl What this means for the implementor is that on some systems wcwidth() can
1410 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1411 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1412 dnl characters). These do not necessarily match the behavior of the terminal
1413 dnl emulator. xterm, for instance, does an optional startup check to find if
1414 dnl this problem (or similar) exists with the system's locale tables, rejecting
1415 dnl them if they are too unreliable.

1594 dnl -----------------
1595 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1596 dnl character-strings.
1598 dnl It is ambiguous because the specification accommodated the pre-ANSI
1599 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1600 dnl compiler other than by costly add-ons. Because of this, the specification
1601 dnl did not take into account the use of const for telling the compiler that
1602 dnl string literals would be in readonly memory.
1604 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1605 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1606 dnl That does not solve the problem of using the block of Xt's strings which
1607 dnl are compiled into the library (and is less efficient than one might want).
1609 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1610 dnl when compiling the library and compiling using the library, to tell the
1611 dnl compiler that String is const.

6885 dnl libraries are compiled in ../../lib
6887 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
6888 dnl to install symbolic links to the rel/abi versions of shared libraries.
6890 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
6891 dnl version when making symbolic links.
6893 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
6894 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
6895 dnl (ex: libncurses.so.<ver>).
6897 dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
