Well, there are a lot of other issues to be fixed if you want to build elfutils on anything non-gcc. We could add a further check for those builtins and sys/param.h and then add a somewhat less trivial version of endian.h and byteswap.h if they are missing. But that would likely involve other compiler extensions or OS-specific headers. br, Ulf
