* infrun.c (IN_SOLIB_TRAMPOLINE): Correct comment, trampolines

Browse Source 
are in the .plt section.
	* minsyms.c (lookup_solib_trampoline_symbol_by_pc,
	find_solib_trampoline_target):  New functions for handling
	stepping into -g compiled shared libraries.
	* symtab.h (lookup_solib_trampoline_symbol_by_pc,
	find_solib_trampoline_target):  Add prototypes.
	* config/tm-sunos.h (IN_SOLIB_TRAMPOLINE, SKIP_TRAMPOLINE_CODE):
	Define to handle stepping into  -g compiled shared libraries.
	* config/tm-sysv4.h (SKIP_TRAMPOLINE_CODE):  Define to handle
	stepping into  -g compiled shared libraries.
	* configure.in:  Add mips-*-sysv4* support.
	* config/mips/mipsv4.mh, config/mips/mipsv4.mt,
	config/mips/tm-mipsv4.h, config/mips/xm-mipsv4.h, mipsv4-nat.c:
	New files for MIPS SVR4 support.
	* Makefile.in:  Update for new mipsv4 files.
	* alpha-tdep.c (heuristic_proc_desc, find_proc_desc):  Use
	read_next_frame_reg to obtain the frame relative stack pointer.
	* mips-tdep.c (heuristic_proc_desc):  Use read_next_frame_reg to
	obtain the frame relative stack pointer.
	* mdebugread.c (parse_partial_symbols, psymtab_to_symtab1):
	Handle stStatic and stStaticProc symbols in stabs-in-ecoff output
	by entering them into the minimal symbol table.
	* printcmd.c (print_scalar_formatted):  Do not try to unpack to
	a long for float formats.
	* solib.c:  Include "elf/mips.h" only if DT_MIPS_RLD_MAP does not
	get defined in <link.h>.
	* solib.c (solib_add):  Add shared library sections to the section
	table of the target before adding the symbols.
	* partial-stab.h:  Relocate static and global functions.
	* dbxread.c (read_dbx_symtab):  Remove unused variable
	end_of_text_address.  Relocate text_addr when passing it
	to end_psymtab.

	For Alpha OSF/1 targets, enable gdb to set breakpoints in shared
	library functions before the executable is run. Retrieve dynamic
	symbols from stripped executables.
	* mipsread.c (read_alphacoff_dynamic_symtab):  New function.
	* mipsread.c (mipscoff_symfile_read):  Use it. Issue warning message
	if no debugging symbols were found.
	* alpha-tdep.c (alpha_skip_prologue):  Silently return the unaltered
	pc if memory at the pc is not accessible and GDB_TARGET_HAS_SHARED_LIBS
	is defined.
	* config/alpha/nm-alpha.h (GDB_TARGET_HAS_SHARED_LIBS):  Define,
	OSF/1 has shared libraries.
