This is not what I meant. A simple reproducer is ideally a piece of C code which shows ;the problem with a minimum of code. In this case, a pice of C code with the #includes required to reproduce the compiler failing is what I'm looking for. > I guess it's the include search order that has ./lib/stdlib.h being included > from sys/cpuset.h rather than the "<stdlib.h>" coded there. That should break including any other header file, too, which includes <stdlib.h>. Why does it only break sys/cpuset.h? > I'm not familiar with building coreutils.
