Hello!

Profiledbootstrap breaks in gengtype-state.c, claiming that "previous"
variable in read_state_structures may be uninitialized.

I have committed attached patch to fix the failure.

2010-11-25  Uros Bizjak  <ubizjak@gmail.com>

	* gengtype-state.c (read_state_structures): Initialize "previous".

Tested on x86_64-pc-linux-gnu {,-m32} with profiledbootstrap.
Committed to SVN mainline.

Uros.
