[RFA] fix some problems in testsuite

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  While trying to test the release candidate
on a ubuntu server i386-pc-linux
a got several UNTESTED related to warnings
issued by gcc.
  It seems that the installed version of gcc 
does generate warnings for format by default.

See
http://sourceware.org/ml/gdb/2009-10/msg00014.html

This patch handles 1),2) and 6)
problems in that email.

Tested on compile farm gcc16,
no changes there... (that gcc seems less picky).

Is this OK?
