-# From the sched_setaffinity(2)'s man page:
-# ~~~~
-# The CPU affinity system calls were introduced in Linux kernel 2.5.8.
-# The library interfaces were introduced in glibc 2.3. Initially, the
-# glibc interfaces included a cpusetsize argument. In glibc 2.3.3,
-# the cpuset size argument was removed, but this argument was
-# restored in glibc 2.3.4.
-# ~~~~
-
-# In addition to that, some vendors ported the system call to 2.4
-# kernels.
-
-# Furthermore, when the function first appeared, the MASK argument was
-# an unsigned long pointer, while later it was made into a cpu_set_t
-# pointer. Systems that have the cpu_set_t version also should have
-# the CPU_ZERO, CPU_SET, etc. macros.
-
-# All this mess means we have to cater for at least 3 different
-# sched_setaffinity prototypes:
-
-# ~~~~
-# int sched_setaffinity (pid_t pid, unsigned int len, unsigned long *mask);
-# int sched_setaffinity (pid_t __pid, size_t __cpusetsize, const cpu_set_t *__cpuset);
-# int sched_setaffinity (pid_t __pid, const cpu_set_t *__mask);
-# ~~~~
-
-# Since we define _GNU_SOURCE in the sources, must do so too in the
-# autoconf tests, as defining _GNU_SOURCE or not exposes
-# sched_setaffinity bits differently.
