Browse Source 
* Makefile.in (DEMANGLE_OPTS):  Add, default to -Dnounderscore.
	* configure.in:  Simplify ncr3000 gdb_host logic, add gdb_target.
	* dwarfread.c (struct_type):  Apply fix from Peggy Fieland for
	proper handling of bit fields.
	* gdbtypes.h (struct type):  Clarify use of field.bitpos.
	* symtab.h:  Fix couple of misspellings in comments.
	* value.h (struct value):  Clarify use of bitpos.
	* value.h (unpack_field_as_long):  Change prototype, returns
	LONGEST.
	* values.c (unpack_field_as_long):  Change return type to LONGEST,
	sign extend unpacked fields that are signed, other rewriting.
	* config/ncr3000.mt:  New target config file.
