re PR bootstrap/84405 (Fails to bootstrap with GCC 4.1.2, GCC 4.2.4)
PR bootstrap/84405
* system.h (BROKEN_VALUE_INITIALIZATION): Define for GCC < 4.3.
* vec.h (vec_default_construct): Use memset instead of placement new
if BROKEN_VALUE_INITIALIZATION is defined.
* hash-table.h (hash_table<Descriptor, Allocator>::empty_slow): Use
memset instead of value initialization if BROKEN_VALUE_INITIALIZATION
is defined.
