1486 dnl -------------------------
1487 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1488 dnl should support line-drawing. Even with Unicode. There is a problem.
1490 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1491 dnl all of those were combined into a page of useful graphics characters.
1493 dnl So far, so good.
1495 dnl However, while they are useful, there are other considerations. CJK
1496 dnl is (because of poor device resolution) often rendered as double-width
1497 dnl characters. So... for these generally-useful characters, what should
1498 dnl be the width (to make them consistent with adjacent characters)?
1500 dnl The obvious choice would have been to make this locale-dependent, and use
1501 dnl wcwidth() to tell applications what the actual width is. That was too
1502 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1504 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1505 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1507 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1508 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1509 dnl instance, it lists half (44/96) of the Latin-1 characters as
1510 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1512 dnl What this means for the implementor is that on some systems wcwidth() can
1513 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1514 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1515 dnl characters). These do not necessarily match the behavior of the terminal
1516 dnl emulator. xterm, for instance, does an optional startup check to find if
1517 dnl this problem (or similar) exists with the system's locale tables, rejecting
1518 dnl them if they are too unreliable.

1698 dnl -----------------
1699 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most

1702 dnl It is ambiguous because the specification accommodated the pre-ANSI
1703 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1704 dnl compiler other than by costly add-ons. Because of this, the specification
1705 dnl did not take into account the use of const for telling the compiler that
1706 dnl string literals would be in readonly memory.
1708 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1709 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1710 dnl That does not solve the problem of using the block of Xt's strings which
1711 dnl are compiled into the library (and is less efficient than one might want).
1713 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1714 dnl when compiling the library and compiling using the library, to tell the
1715 dnl compiler that String is const.

5471 dnl Check if the make-program handles a ".PHONY" target, e.g,. a target which

5475 dnl https://www.austingroupbugs.net/view.php?id=523
5476 dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
5478 dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
5479 dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
5481 dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
5482 dnl date unspecified).
5484 dnl + It was adopted in NetBSD make in June 1995.
5486 dnl + The other BSD make programs are derived from the NetBSD make (and for
5487 dnl that reason are not actually different "implementations").
5489 dnl + Some features of NetBSD make were actually adapted from pmake, which
5490 dnl began as a modified GNU make starting in 1993.
5492 dnl + Version 3.8 of the dmake program in January 1992 also implemented this
