1479 dnl -------------------------
1480 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1481 dnl should support line-drawing. Even with Unicode. There is a problem.
1483 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1484 dnl all of those were combined into a page of useful graphics characters.
1486 dnl So far, so good.
1488 dnl However, while they are useful, there are other considerations. CJK
1489 dnl is (because of poor device resolution) often rendered as double-width
1490 dnl characters. So... for these generally-useful characters, what should
1491 dnl be the width (to make them consistent with adjacent characters)?
1493 dnl The obvious choice would have been to make this locale-dependent, and use
1494 dnl wcwidth() to tell applications what the actual width is. That was too
1495 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1497 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1498 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1500 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1501 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1502 dnl instance, it lists half (44/96) of the Latin-1 characters as
1503 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1505 dnl What this means for the implementor is that on some systems wcwidth() can
1506 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1507 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1508 dnl characters). These do not necessarily match the behavior of the terminal
1509 dnl emulator. xterm, for instance, does an optional startup check to find if
1510 dnl this problem (or similar) exists with the system's locale tables, rejecting
1511 dnl them if they are too unreliable.

1691 dnl -----------------
1692 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1693 dnl character-strings.
1695 dnl It is ambiguous because the specification accommodated the pre-ANSI
1696 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1697 dnl compiler other than by costly add-ons. Because of this, the specification
1698 dnl did not take into account the use of const for telling the compiler that
1699 dnl string literals would be in readonly memory.
1701 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1702 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1703 dnl That does not solve the problem of using the block of Xt's strings which
1704 dnl are compiled into the library (and is less efficient than one might want).
1706 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1707 dnl when compiling the library and compiling using the library, to tell the
1708 dnl compiler that String is const.

5571 dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
5573 dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
5574 dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
5576 dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
5577 dnl date unspecified).
5579 dnl + It was adopted in NetBSD make in June 1995.
5581 dnl + The other BSD make programs are derived from the NetBSD make (and for
5582 dnl that reason are not actually different "implementations").
5584 dnl + Some features of NetBSD make were actually adapted from pmake, which
5585 dnl began as a modified GNU make starting in 1993.
5587 dnl + Version 3.8 of the dmake program in January 1992 also implemented this
5588 dnl GNU make extension, but is less well known than the BSD make.

10083 dnl ---------------
10084 dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
10085 dnl or adapt to the vendor's definitions to get equivalent functionality,
10086 dnl without losing the common non-POSIX features.
10089 dnl $1 is the nominal value for _XOPEN_SOURCE
10090 dnl $2 is the nominal value for _POSIX_C_SOURCE
10092 dnl The default case prefers _XOPEN_SOURCE over _POSIX_C_SOURCE if the
10093 dnl implementation predefines it, because X/Open and most implementations agree
10094 dnl that the latter is a legacy or "aligned" value.
10096 dnl Because _XOPEN_SOURCE is preferred, if defining _POSIX_C_SOURCE turns
10097 dnl that off, then refrain from setting _POSIX_C_SOURCE explicitly.
