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

dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
