throw_allocator.h: Fixes for -fno-exceptions.
2007-06-26 Benjamin Kosnik <bkoz@redhat.com> * include/ext/throw_allocator.h: Fixes for -fno-exceptions. * testsuite/util/testsuite_shared.cc: Same. * testsuite/util/io/illegal_input_error.hpp: Same. * testsuite/util/io/verified_cmd_line_input.cc: Same. * libsupc++/typeinfo (type_info): Correct comment formatting, clarify member access and public interface. * libsupc++/exception: Less compressed comments. * libsupc++/new: Same.
