[svn-r7481] Purpose:
Bug fix
Description:
The MPI_File_set_size() routine on ASCI Red is not able to extend files
so that they are larger than 2GB.
Solution:
Add an extra macro which controls whether MPI_File_set_size() can handle
>2GB offsets or if our "older" way of reading a byte, then writing a byte at
the appropriate offset should be used.
Platforms tested:
FreeBSD 4.9 (sleipnir)
