Based on recent discussion it seems possible that we might start to rely on more of C99. A prerequisite for that is enabling support for that on used compilers. Let's see on which buildfarm members autoconf's AC_PROG_CC_C99() is sufficient to do so. There's probably at least one member where the compiler is too old, but that'd probably be OK. If we go for this permanently we'd likely want to clean out / up a few other configure tests. Note this does not touch the msvc build infrastructure, which'd need separate treatment.
