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

+dnl -------------
+dnl Check if the make-program handles a ".PHONY" target, e.g,. a target which
+dnl acts as a placeholder.
+dnl
+dnl The ".PHONY" feature was proposed in 2011 here
+dnl     https://www.austingroupbugs.net/view.php?id=523
+dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
+dnl
+dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
+dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
+dnl
+dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
+dnl   date unspecified).
+dnl
+dnl + It was adopted in NetBSD make in June 1995.
+dnl
+dnl + The other BSD make programs are derived from the NetBSD make (and for
+dnl   that reason are not actually different "implementations").
+dnl
+dnl + Some features of NetBSD make were actually adapted from pmake, which
+dnl   began as a modified GNU make starting in 1993.
+dnl
+dnl + Version 3.8 of the dmake program in January 1992 also implemented this
+dnl   GNU make extension, but is less well known than the BSD make.

 redirects input to /dev/null, making it ignore the stop/pause commands.
 You can still stop it by pressing the interrupt key.

 makes digits scroll as they change.
 When running on a fast display, the program breaks up the scrolling into
 subsecond repaints, making the operation appear smooth.

+use of POSIX threads, e.g., in ditto, rain, and worm.

 		July 1995 (esr): worms is now in living color! :-)
 
-Options:
-	-f			fill screen with copies of 'WORM' at start.
-	-l <n>			set worm length
-	-n <n>			set number of worms
-	-t			make worms leave droppings
-	-T <start> <end>	set trace interval
-	-S			set single-stepping during trace interval
-	-N			suppress cursor-movement optimization
-
   This program makes a good torture-test for the ncurses cursor-optimization
   code.  You can use -T to set the worm move interval over which movement
   traces will be dumped.  The program stops and waits for one character of
   input at the beginning and end of the interval.
