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.
