Purpose:
Bug Fix
Description:
Trying to create the root group or the working group ("/" or ".") fakes out
HDF5 so that it neither creates a group nor returns an error.
Solution:
H5G_namei now throws an error if it was supposed to insert but didn't.
Platforms tested:
sleipnir, Visual Studio 7 (very minor change)
Misc. update:
