[svn-r24098] 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. I checked it in yesterday. But it turned out to be a false fix. So I'm back it out. Tested on jam - reverse of changes.
