set $i = 0
while $i < 9
  p vec[$i++]@10
end

You can define your own commands and use print, output and echo to format
the output in pretty much any way you want.  Or you could add some
functions to your program that output the structure and call them from
gdb.  The GCC sources have examples of both.
