	* utils.c (fputs_demangled, fprint_symbol):  Remove.
	* utils.c (fprintf_symbol_filtered):  New function which combines

	else with two statements.  Bug reported by Stephane Tsacas
	<slt@isoft.fr>.

Thu Mar  4 17:42:03 1993  John Gilmore  (gnu@cygnus.com)

	* command.c (do_setshow_command):  var_uintegers are unsigned.
	* sparc-tdep.c (save_insn_opcodes, restore_insn_opcodes): 
	unsigned, since they use hex values with the high bit set.

Thu Mar  4 08:22:55 1993  Fred Fish  (fnf@cygnus.com)

	Fixes submitted by Karl Berry (karl@nermal.hq.ileaf.com):

	* dbxread.c (dbx_symfile_init):  Make size of the string table
	size field a define (DBX_STRINGTAB_SIZE_SIZE).  Ensure that the
	offset to the string table is nonzero and handle the nonexistant
	string table case, should it occur.  Ensure that the string table
	size read from the file is reasonable, with a minimum lower bound
	of DBX_STRINGTAB_SIZE_SIZE instead of zero.

	* xm-vaxult2.h:  New file.

	Manual.  This was confusing users into thinking that full cfront
	support was implemented.
	* dwarfread.c (CFRONT_PRODUCER):  Remove, was never really used.
	* eval.c (evaluate_subexp):  For STRUCTOP_PTR pass the arg type
	directly to lookup_struct_elt_type, which will do the
	dereferencing itself.
	* gdbtypes.c (lookup_struct_elt_type):  Expand comments.  Fix
	NULL dereferencing bug for unnamed structs, comment out
	questionable code.
	
Mon Mar  1 17:54:41 1993  John Gilmore  (gnu@cygnus.com)

	* coffread.c (process_coff_symbol):  Change PCC argument correction
	so that it only happens on big-endian targets; so that it only
	happens if the short or char argument is aligned on an int
	boundary; and so that it changes the location, rather than the
	type, of the argument.  These changes tend to parallel similar
	(old) changes in stabsread.c.

	* coffread.c (coff_read_enum_type):  Use the specified size for
	enums, don't assume that they are int-sized.

	* c-valprint.c (c_val_print):  Don't assume enums are the same as
	ints.

	* coredep.c:  Handle NO_PTRACE_H in coredep.c.  Fix by Michael
