60   information size.  A major contribution to debug information size
61   is struct descriptions replicated in several object files. The
62   following flags attempt to reduce this information.  The basic
63   idea is to not emit struct debugging information in the current
64   compilation unit when that information will be generated by
65   another compilation unit.
66
67   Debug information for a struct defined in the current source
68   file should be generated in the object file.  Likewise the
69   debug information for a struct defined in a header should be
70   generated in the object file of the corresponding source file.
71   Both of these case are handled when the base name of the file of
72   the struct definition matches the base name of the source file
73   of the current compilation unit.  This matching emits minimal
74   struct debugging information.
75
76   The base file name matching rule above will fail to emit debug
77   information for structs defined in system headers.  So a second
78   category of files includes system headers in addition to files
79   with matching bases.
80
81   The remaining types of files are library headers and application
82   headers.  We cannot currently distinguish these two types.  */
