It is a bit hard too google, but see e.g. https://users.cs.cf.ac.uk/dave/C/node3.html#SECTION00312000000000000000. I think we should not remove it, but we might add other aliases, and we might discuss the order. I agree with Erik that trying the g++ explicitly first is a good idea. I think we should keep CC, but it can be lower priority, so in that case the preferred order would be `g++ c++ CC`. But I am also curious to what problem you experienced? ------------- PR: https://git.openjdk.org/jdk/pull/12558
