+     there's no way to set the section type to SHT_MIPS_DWARF.  Users have
+     traditionally had to fall back on the more common @progbits instead.
+
+     There's nothing really harmful in this, since bfd will correct
+     SHT_PROGBITS to SHT_MIPS_DWARF before writing out the file.  But it
+     means that, for backwards compatibiltiy, the special_section entries
+     for dwarf sections must use SHT_PROGBITS rather than SHT_MIPS_DWARF.
+
+     Even so, we shouldn't force users of the MIPS .section syntax to
+     incorrectly label the sections as SHT_PROGBITS.  The best compromise
+     seems to be to map SHT_MIPS_DWARF to SHT_PROGBITS before calling the
+     generic type-checking code.  */
