[MINC-development] HDF5 Error trying to read acquisition attributes from a MINC file

[Rick Hoge]

I found that the following function call will suppress the generation of these warnings:

H5Eset_auto(NULL, NULL);

of course that is only curing the symptom, and the cause...

It's documented at 

http://www.hdfgroup.org/HDF5/doc1.6/RM_H5E.html#Error-SetAuto
