Build failure on 32bit

[Alfio Lazzaro]

Hi Michael,
this is interesting...

mp_max_memory_size is the maximum size for a MPI message, which I set to 
2GB (2*2^30), i.e.

mp_max_memory_size = 2*INT(2, KIND=MPI_ADDRESS_KIND)**30 

The error is that I have to subtract 1 on a 32bit system (Thanks Tiziano to 
point me that)... However, this is exact what the HUGE function does, 
therefore I changed the code in the trunk with:

-   INTEGER(KIND=MPI_ADDRESS_KIND), PARAMETER, PRIVATE :: 
mp_max_memory_size = 2*INT(2, KIND=MPI_ADDRESS_KIND)**30 
+   INTEGER(KIND=MPI_ADDRESS_KIND), PARAMETER, PRIVATE :: 
mp_max_memory_size = HUGE(INT(1,KIND=int_4))

Could you try it?

Alfio
