Hui,
Probably we need to remove the trailing ".*" above.  Then, the rest of 
the output will be matched ...

We need append "$mi_gdb_prompt$" to the end of the pattern above to eat 
all the output, otherwise, these output will make troubles to the rest 
of the tests.

I can get some fails on my machine, similar to fails that Pedro pointed 
out.  With these change above, I don't see fails any more.

b.t.w,

+# To make sure set dprintf-style agent get right output.
+mi_gdb_test "pwd" ".*"

This line is odd to me, and looks it only papers over the problem 
somewhere else.
