[svn-r11375] Purpose:
To support irregular collective chunk IO supports for the upcoming 1.6.5 release.
Description:
Should add a macro to detect whether complicated MPI derived datatype works or not.
Solution:
Platforms tested:
AIX 5.1(32bit and 64bit)
Linux 2.4(heping)-mpich 1.2.6
Linux 2.4(NCSA teragrid) -mpich 1.2.5
Altrix(cobalt)
IRIX 6.5- c compiler version 7.4.3(NCAR SGI)
Linux 2.4(tune) - CMPI 2.1.0
