* Changes to keep a full expression as the value of a symbol, not
just a longword:
* struc-symbol.h: New field sy_value.
* as.h: Include expr.h before struc-symbol.h.
* expr.h: Use struct symbol rather than symbolS.
* symbols.c (S_GET_VALUE, S_SET_VALUE): Rewrote to retrieve value
of sy_value field; compile unconditionally, not just if
BFD_ASSEMBLER.
* symbols.h: Compile S_{SG}ET_VALUE prototypes unconditionally.
* write.c (write_object_file): Set BFD symbol value to gas symbol
value.
* config/obj-aout.h, config/obj-bout.h, config/obj-coff.h,
config/obj-coffbfd.h, config/obj-generic.h, config/obj-vms.h
(S_GET_VALUE, S_SET_VALUE): Removed macro definitions.
* config/obj-ieee.c (S_GET_VALUE, S_SET_VALUE): Removed.
* config/obj-coff.h, obj-coffbfd.h: Rewrote several macros to use
S_GET_VALUE rather than ost_entry.n_value.
* config/obj-aout.c (obj_symbol_to_chars), config/obj-bout.c
(obj_symbol_to_chars), config/obj-coff.c (obj_symbol_to_chars),
config/obj-coffbfd.c (symbol_to_chars): Get value to write out
using S_GET_VALUE--don't assume it is already set.
* config/obj-ieee.c (do_symbols): Set BFD symbol value to gas
symbol value.
* config/obj-vms.c (various): Don't assign directly to
S_GET_VALUE; use S_SET_VALUE instead.
