The problem with clang is that it claims to implement -std=gnu99 but doesn't really. We now have a configure check to make sure the features used in the code base are actually supported by the compiler. So as soon as clang gets the needed features it should just work. Various people have worked on supporting clang as compiler, but it is a lot of work and nobody succeeded doing it without making the code much harder to maintain. But in general elfutils patches to clean up the code and support alternative compilers (or linkers, libc, kernels, etc.) are accepted and integrated as long as they improve the code base and don't make it hard to maintain. But the first target of elfutils is a normal GNU/Linux system. You might want to look at the mailinglist archives to find various attempts. Including a discussion of replacing nested functions with blocks. Which wasn't accepted because nobody seemed to believe it actually improved the code. Cheers, Mark
