In gdb4.7 (sparc target, sparc host),
built to run with gcc2.2.2 with some modifications to dbxout.c,
I note these problems.

1:  Inside of a member function, the class members are not implicitly reachable;
instead of saying "print x", one must say "print this->x".
Is this a bug or a feature?

2:  I can not put a breakpoint on the destructor for Thing,
eg on Thing::~Thing; the breakpoint ends up on the constructor Thing::Thing
instead.  This may be because my name mangling configuration
(both in gcc2.2.2/dbxout.c and in gdb4.7(GCC_MANGLE_BUG)) may be
screwed up.  (My version of gcc2.2.2/dbxout.c has undergone several
patches from the net, as well as gdb/gcc.patch)

3: othergdb4.7 users on site who are debugging big programs complain that
'where' takes several minutes to complete.
