Merge pull request #2593 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:hdf5_1_12 to hdf5_1_12 * commit '1a9316668131ab84d99a557789bdef9763de5ed2': Revise gnu-*flags and cmake/HDF*CompilerFlags.cmake files to add warning flags for GCC compilers version 4.8 and above. Removed files from gnu-warnings that only apply to versions < 4.8. Consolidated warnings from versions < 4.8 that apply to versions >= 4.8 into the 4.8 warnings files.
