The old way (using #undef in tm.h) was ugly and asking for
trouble, because it makes it possible for some file to use the
wrong definition. Move definition of HOST_CHAR_BIT after definition
of TARGET_CHAR_BIT.

rather than retrieving them from the bfd. Also changed to keep
the pending list with the psymtab rather than the objfile (each
psymtab for a single objfile points to the same pending list).

the sym_fns.

give it a default definition.
(mips_skip_prologue): Skip instructions which initialize $gp
register.
(in_sigtramp): New procedure, moved in from mipsread.c.

the number for an M88110 extended register by just returning the
address of r0.
* m68k-tdep.c (m68k_saved_pc_after_call): Get rid of

m68k_saved_pc_after_call.
* Remove all Sun3 specific stuff.
* (FIX_CALL_DUMMY): Cast arg to bfd_putb32 to unsigned char *.

REGISTER_CONVERTIBLE is defined, otherwise just copy the content.
Pass desired type to REGISTER_CONVERT_TO_*.

* delta68-nat.c: Add "[0]" in offsetof argument.

etc. This is to make it host on Solaris, AIX, etc.
* Makefile.in: Reflect removed nindy-share files.
* config/i960/nindy960.mt (TDEPFILES): Remove ttybreak.o.
<memory.h>.
Include <malloc.h> rather than declaring malloc functions ourself.

(EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE, EXTRACT_STRUCT_VALUE_ADDRESS):
Add FIXME's for h8/300h. Some thought needed here.
