Browse Source 
2009-05-07  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/ext/throw_allocator.h (throw_allocator_base): Avoid
	out of line member functions definitions.
	(throw_allocator_base::_S_g, _S_map, _S_throw_prob, _S_label):
	Remove, use static locals instead.
	(throw_allocator_base::do_check_allocated, print_to_string): Declare.
	* src/throw_allocator.cc: New.
	* src/Makefile.am: Add.
	* config/abi/pre/gnu.ver: Add exports.
	* src/Makefile.in: Regenerate.
