1064 dnl -------------------------
1065 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1066 dnl should support line-drawing. Even with Unicode. There is a problem.
1068 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1069 dnl all of those were combined into a page of useful graphics characters.
1071 dnl So far, so good.
1073 dnl However, while they are useful, there are other considerations. CJK
1074 dnl is (because of poor device resolution) often rendered as double-width
1075 dnl characters. So... for these generally-useful characters, what should
1076 dnl be the width (to make them consistent with adjacent characters)?
1078 dnl The obvious choice would have been to make this locale-dependent, and use
1079 dnl wcwidth() to tell applications what the actual width is. That was too
1080 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1082 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1083 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1085 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1086 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1087 dnl instance, it lists half (44/96) of the Latin-1 characters as
1088 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1090 dnl What this means for the implementor is that on some systems wcwidth() can
1091 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1092 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1093 dnl characters). These do not necessarily match the behavior of the terminal
1094 dnl emulator. xterm, for instance, does an optional startup check to find if
1095 dnl this problem (or similar) exists with the system's locale tables, rejecting
1096 dnl them if they are too unreliable.

5789 dnl the build-tree, i.e., by making use of the libraries that are compiled in

5793 dnl libraries are compiled in ../../lib
5795 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
5796 dnl to install symbolic links to the rel/abi versions of shared libraries.
5798 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
5799 dnl version when making symbolic links.

5802 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
5803 dnl (ex: libncurses.so.<ver>).
