It is not that much related to the C programming language, nor to the GNU
implementation for it (compiler, linker, standard library), nor with any
other GNU programming language implementation (like the ones for C++ or Ada),
it is the GNU build system (autotools, make) which adds the complexity.

Please don't, it is still useful, however I would be thankful if you or Yavor
also add the use cases from the latest discussions, even doing them verbatim.

Yes, it is, and I'm happier with much simpler beasts like icmake for instance.
