Subject: [charm] Charm 6.7.1 MetisLB bug

Hi,

I was recently compiling charm++ 6.7.1 with Metis on a new machine, and ran across a bug in the MetisLB.C and and TeamLB.C and TeamLB.h files.

It appears that Metis type defs all arguments to its functions as idx_t, which in the Metis library I have is a 64 bit int, but the charm code declares some of its variables as simply int and then passes these pointers to the function.  The gcc compiler (4.8) won't compile, because it cannot convert an int* to a long int *.

Attached is a patch to correctly define the types needed by the Metis functions using the Metis idx_t type def.
