+Define this macro if you with to define command-line switches that modify the

+
+For each switch, you can include a string to be appended to the first
+part of the configuration name or a string to be deleted from the
+configuration name, if present. The definition should be an initializer
+for an array of structures. Each array element should have three
+elements: the switch name (a string constant, including the initial
+dash), one of the enumeration codes @code{ADD} or @code{DELETE} to
+indicate whether the string should be inserted or deleted, and the string
+to be inserted or deleted (a string constant).
+
+For example, on a machine where @samp{64} at the end of the
+configuration name denotes a 64-bit target and you want the @samp{-32}
+and @samp{-64} switches to select between 32- and 64-bit targets, you would
