The HOWTO Macro
DESCRIPTION
- The HOWTO define is horrible and will go away.
+ The HOWTO macro fills in a reloc_howto_type (a typedef for
+ const struct reloc_howto_struct).

-. { (unsigned) C, R, S, B, P, BI, O, SF, NAME, INPLACE, MASKSRC, MASKDST, PC }
-
-DESCRIPTION
- And will be replaced with the totally magic way. But for the
- moment, we are compatible, so do it this way.
