+   following flags attempt to reduce this information.  The basic
+   idea is to not emit struct debugging information in the current
+   compilation unit when that information will be generated by
+   another compilation unit.
+
+   Debug information for a struct defined in the current source
+   file should be generated in the object file.  Likewise the
+   debug information for a struct defined in a header should be
+   generated in the object file of the corresponding source file.
+   Both of these case are handled when the base name of the file of
+   the struct definition matches the base name of the source file
+   of the current compilation unit.  This matching emits minimal
+   struct debugging information.
+
+   The base file name matching rule above will fail to emit debug
+   information for structs defined in system headers.  So a second
+   category of files includes system headers in addition to files
+   with matching bases.
+
+   The remaining types of files are library headers and application
+   headers.  We cannot currently distinguish these two types.  */
