* config/i386/tm-cygwin.h: include tm-i386.h instead of tm-i386v.h.  This fixes
errors in "long long" handling for 'finish' and 'return' commands.
* win32-nat.c (safe_symbol_file_add_stub): Avoid adding a shared library if it
has already been loaded.
(safe_symbol_file_add_cleanup): Don't mess with stderr or we won't see any
error messages.
(safe_symbol_file_add): Ditto.
(solib_symbols_add): Make static.  Accept 'from_tty' parameter.  Pass it to
safe_symbol_file_add.
(core_dll_symbols_add): Accomodate extra solib_symbols_add parameter.
(child_solib_add): Ditto.
* win32-nat.c (handle_exception): Don't print "first chance" exceptions.
(get_child_debug_event): Continue from exceptions if !handle_exception.
