1344 dnl -------------------------
1345 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1346 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1347 dnl
1348 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1349 dnl all of those were combined into a page of useful graphics characters.
1350 dnl
1351 dnl So far, so good.
1352 dnl
1353 dnl However, while they are useful, there are other considerations.  CJK
1354 dnl is (because of poor device resolution) often rendered as double-width
1355 dnl characters.  So... for these generally-useful characters, what should
1356 dnl be the width (to make them consistent with adjacent characters)?
1357 dnl
1358 dnl The obvious choice would have been to make this locale-dependent, and use
1359 dnl wcwidth() to tell applications what the actual width is.  That was too
1360 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1361 dnl See for example
1362 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1363 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1364 dnl
1365 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1366 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1367 dnl instance, it lists half (44/96) of the Latin-1 characters as
1368 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1369 dnl
1370 dnl What this means for the implementor is that on some systems wcwidth() can
1371 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1372 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1373 dnl characters).  These do not necessarily match the behavior of the terminal
1374 dnl emulator.  xterm, for instance, does an optional startup check to find if
1375 dnl this problem (or similar) exists with the system's locale tables, rejecting
1376 dnl them if they are too unreliable.

1556 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1557 dnl character-strings.
1558 dnl
1559 dnl It is ambiguous because the specification accommodated the pre-ANSI
1560 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1561 dnl compiler other than by costly add-ons.  Because of this, the specification
1562 dnl did not take into account the use of const for telling the compiler that
1563 dnl string literals would be in readonly memory.
1564 dnl
1565 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1566 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1567 dnl That does not solve the problem of using the block of Xt's strings which
1568 dnl are compiled into the library (and is less efficient than one might want).
1569 dnl
1570 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1571 dnl when compiling the library and compiling using the library, to tell the
1572 dnl compiler that String is const.

6833 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
6834 dnl libraries are compiled in ../../lib
6835 dnl
6836 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure

6838 dnl
6839 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
6840 dnl version when making symbolic links.
6841 dnl
6842 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
6843 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
6844 dnl (ex: libncurses.so.<ver>).
6845 dnl
