+   We allow the difference of two symbols when the subtract symbol is
+   local to the relocation.  This is implemented using R_HPPA_COMPLEX.
+
+   This has some limitations.  Difference expressions only work between
+   symbols in the same segment/quadrant of a module since the HP dynamic
+   loader relocates the text and data segments independently.  Thus, a
