* Makefile.in (VERSION): Bump to 4.5.2.
* 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.
