        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
+       option lets you choose the prefix for these wrapped variables.

        Suppress the configure script's check for Ada95, do not build the
        Ada95 binding and related demo.
