[svn-r24095] Issue 8500 - H5detect.c has trouble to find info for long double with GCC 4.8. A user in the forum found the
problem in H5detect.c (uninitialized buffer) and provided the solution. Allen and I verified it.
Tested with h5committest and CMake on jam, koala, ostrich, playtus, and Allen's virtual machine.
