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.
1067 dnl
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.
1070 dnl
1071 dnl So far, so good.
1072 dnl
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)?
1077 dnl
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.
1081 dnl See for example
1082 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1083 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1084 dnl
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.
1089 dnl
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

5961 dnl
5962 dnl Notes:
5963 dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
5964 dnl the build-tree, i.e., by making use of the libraries that are compiled in
5965 dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
5966 dnl shared library since that can lead to unexpected results at runtime.
5967 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
5968 dnl libraries are compiled in ../../lib
5969 dnl
5970 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
5971 dnl to install symbolic links to the rel/abi versions of shared libraries.
5972 dnl
5973 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
5974 dnl version when making symbolic links.
5975 dnl
5976 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
5977 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
5978 dnl (ex: libncurses.so.<ver>).
5979 dnl
5980 dnl Some loaders leave 'so_locations' lying around.  It's nice to clean up.
