+
+       * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
+       function.  Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
+       reloc for "foo".
+       (i386_operand): Don't look up section symbol for
+       undefined_section.
+       (reloc): Always permit return of 8- and 16-bit relocation types.
+       Add a space after "pc-relative" in the error message.
+       (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
+       BFD_RELOC_386_GOTOFF relocs.
+       (i386_operand): For any GOTOFF reloc, convert it to a BFD_RELOC_32
+       with a "foo-GOT" value.
+       * config/tc-i386.h (i386_validate_fix): Declare it.
+       (TC_VALIDATE_FIX): New macro -- call it.
+       (NOP_OPCODE): Cast to `char' to avoid compiler warnings.
+
+       * as.h: If __STDC__ is not defined and varargs.h is available, use
+       it rather than stdarg.h.
+
+       * write.h (struct fix): Added new bitfield fx_plt, for fixups
+       referring to PLT entries.
+       * write.c (fix_new_internal): Initialize fx_plt to zero.
+       (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
+       Don't adjust fx_offset by frag address, since S_GET_VALUE now
+       includes the frag address.
+       (fixup_segment): Changed local var PCREL to type int, added PLT.
+       If PC-relative fixup refers to a PLT entry for a symbol in the
+       current section, don't reduce it.
+
+       * write.c (adjust_reloc_syms):  Exit loop through a label.  If
+       DEBUG5 is defined, print out each fixup before and after
+       processing.
+       (fixup_segment): If DEBUG5 is defined, print out each fixup before
+       and after processing.
+       (print_fixup): Added prototype.  Show address on first line.  Show
+       fx_offset and fx_subsy.  [!BFD_ASSEMBLER]: Only show fx_r_type if
+       NEED_FX_R_TYPE is defined.
+
+       * symbols.c (print_symbol_value_1): Check S_IS_LOCAL, S_IS_EXTERN,
+       S_IS_DEBUG, S_IS_DEFINED also.

        * Makefile.in (all): Depend on .gdbinit.
