* config/m68k/dpx2.mh (NATDEPFILES): Remove duplicate inclusion

Browse Source 
of inftarg.o.
	* config/m68k/tm-dpx2.h (CANNOT_STORE_REGISTER):  Define to inhibit
	writing of floating registers, the dpx2 kernel disallows it.
	* irix5-nat.c (LM_ADDR):  The loaded address of the shared library
	is contained in o_praw.
	* irix5-nat.c (solib_map_sections):  Adjust sections by the
	difference between the loaded address and the prelinked address.
	* irix5-nat.c (solib_address):  Use LM_ADDR for the loaded start
	address.
	* mdebugread.c (parse_symbol):  Do not relocate stEnd/scText
	symbols, their value is absolute.
	* mdebugread.c (parse_partial_symbols):  Handle Irix 5.2 shared
	libraries fh->adr fields of zero. Relocate minimal symbol values
	upon readin. Relocate non-stabs symbols upon readin.
	* mdebugread.c (psymtab_to_symtab_1):  Use pst->textlow for the
	start address of the outermost block.
	* mdebugread.c (parse_lines, parse_procedure):  Pass in pst
	instead of section_offsets and use relocated pst->textlow for
	line number and procedure address relocations.

	From gmo@MicroUnity.com (Guillermo A. Loyola):
	* mdebugread.c (parse_symbol, parse_partial_symbols, cross_ref):
	Handle SGI Irix5 stIndirect symbol type.
