* dwarf2dbg.c (INSERT_DIR_SEPARATOR): New macro.  Handles the insertion of a
  directory separator character into a string at a given offset.  Uses
  heuristics to decide when to use a backslash character rather than a
  forward-slash character.
  (dwarf2_directive_loc): Use the macro.
  (out_debug_info): Likewise.

/* We need to decide which character to use as a directory separator.
Just because HAVE_DOS_BASED_FILE_SYSTEM is defined, it does not
necessarily mean that the backslash character is the one to use.
Some environments, eg Cygwin, can support both naming conventions.
So we use the heuristic that we only need to use the backslash if
the path is an absolute path starting with a DOS style drive
selector. eg C: or D: */
