1037 dnl -------------------------
1038 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1039 dnl should support line-drawing. Even with Unicode. There is a problem.
1041 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1042 dnl all of those were combined into a page of useful graphics characters.
1044 dnl So far, so good.
1046 dnl However, while they are useful, there are other considerations. CJK
1047 dnl is (because of poor device resolution) often rendered as double-width
1048 dnl characters. So... for these generally-useful characters, what should
1049 dnl be the width (to make them consistent with adjacent characters)?
1051 dnl The obvious choice would have been to make this locale-dependent, and use
1052 dnl wcwidth() to tell applications what the actual width is. That was too
1053 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1055 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1056 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1058 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1059 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1060 dnl instance, it lists half (44/96) of the Latin-1 characters as
1061 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1063 dnl What this means for the implementor is that on some systems wcwidth() can
1064 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1065 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1066 dnl characters). These do not necessarily match the behavior of the terminal
1067 dnl emulator. xterm, for instance, does an optional startup check to find if
1068 dnl this problem (or similar) exists with the system's locale tables, rejecting
1069 dnl them if they are too unreliable.

5740 dnl the build-tree, i.e., by making use of the libraries that are compiled in
5741 dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
5742 dnl shared library since that can lead to unexpected results at runtime.
5743 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
5744 dnl libraries are compiled in ../../lib
5746 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
5747 dnl to install symbolic links to the rel/abi versions of shared libraries.
5749 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
5750 dnl version when making symbolic links.
5752 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
5753 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
5754 dnl (ex: libncurses.so.<ver>).
5756 dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
