1024 dnl -------------------------
1025 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1026 dnl should support line-drawing. Even with Unicode. There is a problem.
1028 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1029 dnl all of those were combined into a page of useful graphics characters.
1031 dnl So far, so good.
1033 dnl However, while they are useful, there are other considerations. CJK
1034 dnl is (because of poor device resolution) often rendered as double-width
1035 dnl characters. So... for these generally-useful characters, what should
1036 dnl be the width (to make them consistent with adjacent characters)?
1038 dnl The obvious choice would have been to make this locale-dependent, and use
1039 dnl wcwidth() to tell applications what the actual width is. That was too
1040 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1042 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1043 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1045 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1046 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1047 dnl instance, it lists half (44/96) of the Latin-1 characters as
1048 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1050 dnl What this means for the implementor is that on some systems wcwidth() can
1051 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1052 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1053 dnl characters). These do not necessarily match the behavior of the terminal
1054 dnl emulator. xterm, for instance, does an optional startup check to find if
1055 dnl this problem (or similar) exists with the system's locale tables, rejecting
1056 dnl them if they are too unreliable.

5714 dnl the build-tree, i.e., by making use of the libraries that are compiled in

5717 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
5718 dnl libraries are compiled in ../../lib
5720 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
5721 dnl to install symbolic links to the rel/abi versions of shared libraries.
5723 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
5724 dnl version when making symbolic links.
5726 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
5727 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
5728 dnl (ex: libncurses.so.<ver>).
5730 dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
