There is no "modern" C but "C with additional niceties". And those additions are usually low key enough to be adopted by a good portion of the compilers out there. When you have a C code base or experience with C those features may be enough not to make a complex transition. Having a simple tool evolve a bit may be what you need as opposed to making the change to a much more complex tool.
