configure.ac: set C and C++ dialects
Make sure that the compiler always assumes the same C dialect, to prevent unexpected compiler errors when building with older compilers (on other Linux distrubtions like in OBS, or in docker). Use gnu89 and gnu++03, because that is what the code currently compiles with.
