+ --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 before version 1.08 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"
+ terminfo entry to use this setting.
