Subject:         * symtab.h (DESTRUCTOR_PREFIX_P): New macro to check if
 physname         is a C++ destructor.         * symtab.c (gdb_mangle_name):
 Use it.         * symtab.c (find_methods): Do not add destructors to choice
 list         for constructors.         * symtab.c (decode_line_1): Make
 breakpoints on destructors work         for gcc-2.x again.
