* defs.h (demangle_and_match):  Remove prototype.
	* dwarfread.c (STREQ, STREQN):  Remove macros, replaced with STREQ
	  and STREQN defined in defs.h.
	* dwarfread.c (set_cu_language):  For completely unknown languages,
	  try to deduce the language from the filename.  Retain behavior
	  that for known languages we don't know how to handle, we use
	  language_unknown.
	* dwarfread.c (enum_type, symthesize_typedef):  Initialize language
	  and demangled name fields in symbol.
	* dwarfread.c, mipsread.c, partial-stab.h:  For all usages of
	  ADD_PSYMBOL_TO_LIST, add language and objfile parameters.
	* dwarfread.c (new_symbol):  Attempt to demangle C++ symbol names
	  and cache the results in SYMBOL_DEMANGLED_NAME for the symbol.
	* elfread.c (STREQ):  Remove macro, use STREQ defined in defs.h.
	  Replace usages throughout.

	  B_CLRALL):  Moved from symtab.h to gdbtypes.h.
	* infcmd.c (jump_command):  Remove code to demangle name and add
	  it to a cleanup list.  Now just use SYMBOL_DEMANGLED_NAME.

	* minsyms.c (lookup_minimal_symbol):  Indent comment to match code.
	* minsyms.c (install_minimal_symbols):  Attempt to demangle symbol

	* stabsread.c (demangle.h):  Include.
	* stabsread.c (define_symbol):  Attempt to demangle C++ symbol
	  names and cache them in the SYMBOL_DEMANGLED_NAME field.
	* stack.c (return_command):  Remove explicit demangling of name
	  and use of cleanups.  Just use SYMBOL_DEMANGLED_NAME.
	* symfile.c (demangle.h):  Include.
	* symfile.c (add_psymbol_to_list, add_psymbol_addr_to_list):  Fix
	  to match macros in symfile.h and allow them to be compiled
	  if INLINE_ADD_PSYMBOL is not true.
	* symfile.h (INLINE_ADD_PSYMBOL):  Default to true if not set.
	* symfile.h (ADD_PSYMBOL_*):  Add language and objfile parameters.
	  Add code to demangle and cache C++ symbol names.  Use macro form
	  if INLINE_ADD_PSYMBOL is true, otherwise use C function form.
	* symmisc.c (add_psymbol_to_list, add_psymbol_addr_to_list):
	  Remove, also defined in symfile.c, which we already fixed.

	  prototype to match.
	* symtab.c (completion_list_add_symbol):  Name changed to
	  completion_list_add_name.
	* symtab.c (COMPLETION_LIST_ADD_SYMBOL):  New macro, adds both
	  the normal symbol name and the cached C++ demangled name.

	  lookup_demangled_block_symbol):  Remove prototypes and functions.
	* symtab.c (lookup_symbol):  Remove use of expensive_mangler,

	* symtab.c (completion_list_add_symbol):  Rewrite to use cached
	  C++ demangled symbol names.
	* symtab.h:  Much reformatting of structures and such to add
	  whitespace to make them more readable, and make them more
	  consistent with other gdb structure definitions.
	* symtab.h (general_symbol_info): New struct containing fields
	  common to all symbols.
	* symtab.h (SYMBOL_LANGUAGE, SYMBOL_DEMANGLED_NAME,

	* buildsym.c (end_symtab):  Update the source language in the
	  allocated symtab to match what we have been using.

#include "solib.h" /* Support for shared libraries. */
/* For SVR4 shared libraries, each call to a library routine goes through
a small piece of trampoline code in the ".init" section. Although each
of these fragments is labeled with the name of the routine being called,
the gdb symbol reading code deliberately ignores them so it won't confuse
them with the real functions. It does however know about the label that
precedes all of the fragments, which is "_init". Thus when we lookup a
function that corresponds to a PC value which is in one of the trampoline
fragments, we'll appear to be in the function "_init". The following
macro will evaluate to nonzero when NAME is valid and matches "_init".
The horribly ugly wait_for_inferior() routine uses this macro to detect
when we have stepped into one of these fragments. */
