 @item
+A variable record to define a variable used to store option
+information.  These records have two fields: the string
+@samp{TargetVariable}, and a declaration of the type and name of the
+variable, optionally with an initializer (but without any trailing
+@samp{;}).  @samp{TargetVariable} is a combination of @samp{Variable}
+and @samp{TargetSave} records in that the variable is defined in the
+@code{gcc_options} structure, but these variables are also stored in
+the @code{cl_target_option} structure.  The variables are saved in the
+target save code and restored in the target restore code.

+@item
+A variable record to record any additional files that the
+@file{options.h} file should include.  This is useful to provide
+enumeration or structure definitions needed for target variables.
+These records have two fields: the string @samp{HeaderInclude} and the
+name of the include file.

+@item
+A variable record to record any additional files that the
+@file{options.c} file should include.  This is useful to provide
+inline functions needed for target variables and/or @code{#ifdef}
+sequences to properly set up the initialization.  These records have
