* dcrt0.cc (dll_crt0_1): Move debug_init call back to here. Avoid a compiler

warning.
* shared.cc (memory_init): Remove debug_init call.
* debug.h (handle_list): Change "clexec" to "inherited".
* debug.cc: Remove a spurious declaration.
(setclexec): Conditionalize away since it is currently unused.
(add_handle): Use inherited field rather than clexec.
(debug_fixup_after_fork_exec): Ditto.  Move debugging output to delete_handle.
(delete_handle): Add debugging output.
* fhandler.cc (fhandler_base::set_inheritance): Don't bother setting
inheritance in debugging table since the handle was never protected anyway.
(fhandler_base::fork_fixup): Ditto.
* exceptions.cc (debugger_command): Revert.
