1416 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1417 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1418 dnl
1419 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1420 dnl all of those were combined into a page of useful graphics characters.
1421 dnl
1422 dnl So far, so good.
1423 dnl
1424 dnl However, while they are useful, there are other considerations.  CJK
1425 dnl is (because of poor device resolution) often rendered as double-width
1426 dnl characters.  So... for these generally-useful characters, what should
1427 dnl be the width (to make them consistent with adjacent characters)?
1428 dnl
1429 dnl The obvious choice would have been to make this locale-dependent, and use
1430 dnl wcwidth() to tell applications what the actual width is.  That was too
1431 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1432 dnl See for example
1433 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1434 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1435 dnl
1436 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1437 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1438 dnl instance, it lists half (44/96) of the Latin-1 characters as
1439 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1440 dnl
1441 dnl What this means for the implementor is that on some systems wcwidth() can
1442 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1443 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1444 dnl characters).  These do not necessarily match the behavior of the terminal
1445 dnl emulator.  xterm, for instance, does an optional startup check to find if
1446 dnl this problem (or similar) exists with the system's locale tables, rejecting
1447 dnl them if they are too unreliable.

1632 dnl compiler other than by costly add-ons.  Because of this, the specification
1633 dnl did not take into account the use of const for telling the compiler that
1634 dnl string literals would be in readonly memory.

7070 dnl Attempt to determine the appropriate CC/LD options for creating a shared
7071 dnl library.
7072 dnl
7073 dnl Notes:
7074 dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
7075 dnl the build-tree, i.e., by making use of the libraries that are compiled in
7076 dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
7077 dnl shared library since that can lead to unexpected results at runtime.
7078 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
7079 dnl libraries are compiled in ../../lib
7080 dnl
7081 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
7082 dnl to install symbolic links to the rel/abi versions of shared libraries.
7083 dnl
7084 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
7085 dnl version when making symbolic links.
7086 dnl
7087 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
7088 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
7089 dnl (ex: libncurses.so.<ver>).
7090 dnl
7091 dnl Some loaders leave 'so_locations' lying around.  It is nice to clean up.
