clock_gettime() wasn't being found, so some configure changes
were needed to set an appropriate POSIX level and use a C99
compiler. This required several compiler flag changes.
Autotools only
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.
* commit '5ea58acf8a2bdf8ca19d4c86d9ef94fbc4ac449f':
Add missing ')'.
Add C++ warnings treated as error for autotools builds.
Move macro ADD_H5_CFLAGS to cmake_ext_mod/HDFMacros.cmake and remove duplicate versions.
Address PR suggestions and add overlooked GCC compiler version flags.
Don't add general warnings flags for unsupported old versions of gcc and g++ (older than gcc/g++ 4.2). Correct gnu-cxxflags to determine warnings flags to be added based on C++ compiler version instead of C compiler version.
