[svn-r7044] Purpose:

Browse Source 
Bug fix.

Description:
the MPI_Get_count test does not work correctly (the macro name
MPI_GET_COUNT_WORKS is not even used in source code.) For some
reason, this test sometimes hangs in AIX.

Solution:
Blocked out the test for now and removed the code later when
things are verified to be correct.

Platforms tested:
h5committested.
ALso tested in Copper (32/64bit parallel, 32 bit serial).
