Purpose:

Add the known problem for IRIX6.5 C version >7.4.
Description:
Somehow SGI's MPI implementation doesn't free MPI_TYPE_entries,
So for large application to use MPI derived datatype, environment
variable MPI_TYPE_MAX needs to be reset.
Solution:

Platforms tested:

Known Problems
==============
* On IRIX6.5, when C compiler version >7.4, the complicate MPI derived data type
code will work. However, the user should be aware to enlarge MPI_TYPE_MAX environment
variable to some certian value in order to use collective irregular selection code.
For example, the current parallel HDF5 test needs to enlarge MPI_TYPE_MAX to
200,000 to make the test pass.
* The dataset created or rewritten with the v1.6.3 library or after can't
be read with the v1.6.2 library or before when Fletcher32 EDC(filter) is
enabled. There was a bug in the calculating code of the Fletcher32
