     --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.  The configure script
-	will automatically apply a suitable ".map" file to provide this
-	information for Linux.  Solaris mapfiles differ:

+
+	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
+	b) wildcards are not accepted, except for a special case of "_*".
 	c) each symbol listed in the map file must exist in the library
 
-	Use "objdump -T" on a library to see the annotations.
+	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.
