+    --with-tparm-arg[=XXX]
+	Override the type used for tparm() arguments, which normally is a

+	better choice would be intptr_t, which was not available at the time

     --with-trace
 	Configure the trace() function as part of the all models of the ncurses
 	library.  Normally it is part of the debug (libncurses_g) library only.
 
+    --with-versioned-syms[=XXX]
+	The Solaris, GNU and reportedly some other linkers (ld) accept a
+	"--version-script" option which tells the linker to annotate the
+	resulting objects with version identifiers.
+
+	Use "objdump -T" on a library to see the annotations.
+
+	The configure script attempts to automatically apply a suitable ".map"
+	file to provide this information for Linux.  Solaris mapfiles differ:
+
+	a) comments are not accepted
+	b) wildcards are not accepted, except for a special case of "_*".
+	c) each symbol listed in the map file must exist in the library
+
+	The Solaris limitations conflict with the development goal of providing
+	a small set of ".map" files as examples, which cover the most common
+	configurations.  Because that coverage is done by merging together
+	several builds, some symbols will be listed in the the ".map" files
+	that do not happen to be present in one configuration or another.
+
+	The sample ".map" (and ".sym") files are generated using a set of
+	scripts which build several configurations for each release version,
+	checking to see which of the "_nc_" symbols can be made local.  In
+	addition to the ncurses libraries and programs, the symbols used
+	by the "tack" program are made global.
+
+	These sample ".map" files will not cover all possible combinations.
+	In some cases, e.g., when using the --with-weak-symbols option, you
+	may prefer to use a different ".map" file by setting this option's
+	value.
+
+    --with-xterm-kbs=XXX
+	Configure xterm's terminfo entries to use either BS (^H, i.e., ASCII
+	backspace) or DEL (^?, or 127).  XXX can be BS (or bs, 8) or DEL
+	(or del, 127).
+
+	During installation, the makefile and scripts modifies the "xterm+kbs"

     --with-valgrind
 	For testing, compile with debug option.
 	This also sets the --disable-leaks option.
 
+    --with-wrap-prefix=XXX
+	When using the --enable-reentrant option, ncurses redefines variables
+	that would be global in curses, e.g., LINES, as a macro that calls a
+	"wrapping" function which fetches the data from the current SCREEN
+	structure.  Normally that function is named by prepending "_nc_" to the
+	variable's name.  The function is technically private (since portable
+	applications would not refer directly to it).  But according to one
+	line of reasoning, it is not the same type of "private" as functions
+	which applications should not call even via a macro.  This configure
