* 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.
