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.

That should break including any other header file, too, which includes
<stdlib.h>.  Why does it only break sys/cpuset.h?

Sorry, but this is not the right thing to do to fix such an issue.
