  and <code>.xdata</code> sections into the final binary.
  This helps with debugging and profiling binaries using native tools, such as WinDbg.
  Note that until now, C functions' SEH exception handlers were not being honored,
  so this change may cause some programs to behave differently.
  <code>-linkmode=external</code> is not affected by this change, as external linkers
  already preserve SEH information.
