[svn-r6757] 
Purpose: Bug fix

Description: on Cray T90IEEE compact storage test (in test_misc8)
             fails since dataset dimensions are too big; dataset
             will not fit into the message header.

Solution: Reduced dimension sizes from 100 to 50.

Platforms tested: h5committested on arabica and mod4; verbena failed
                  because of the F90 license problem. I tested on verbena
                  by hand and C only; Cray T90IEEE
