[PATCH] unpack-trees.c: work around run-time array initialization flaw on IRIX 6.5

The c99 MIPSpro Compiler version 7.4.4m on IRIX 6.5 does not properly
initialize run-time initialized arrays. An array which is initialized with
fewer elements than the length of the array should have the unitialized
elements initialized to zero. This compiler does perform proper
initialization when static initialization parameters are used. So, work
around this by initializing with static elements, followed by a simple
assignment.
