Hello,

This is my second patch for GFortran. This patch adds a linked list to 
keep track of the allocated memory of all static coarrays and ensures 
that at the end of the program the memory is freed.

Additionally, I use MPI_Allgather in mpi.c to ensure that all images 
know the address of the stored memory in the other images. This will be 
needed when the images start sending data to each other.

There is no test case attached because there is no way to automatically 
test for allocated memory.

Here is my ChangeLog to go into libgfortran/ChangeLog:

2011-06-16  Daniel Carrera  <dcarrera@gmail.com>

	* caf/single.c (_gfortran_caf_register): Store the address
	of all static coarrays in a linked list.
	(_gfortran_caf_finalize): Free memory of staic coarrays.
	* caf/mpi.c (_gfortran_caf_register): Store the address
	of all static coarrays in a linked list. Initialize MPI
	if necessary.
	(_gfortran_caf_finalize): Free memory of staic coarrays.
	(_gfortran_caf_init): Check if MPI is already initialized
	before initializing again.
	* caf/libcaf.h: Add a type to caf_register_t to distinguish
	static coarrays and add the type caf_static_t to make the
	linked list of static coarrays.

Cheers,
Daniel.
