dnl An autoconf script to automatically configure ACE.
dnl Process this file with autoconf to produce a configure script.
dnl Statically (i.e. at autoconf-time) determine the version of ACE.
dnl This is necessary since the version argument to AC_INIT is
dnl supposed to be a static value, not a dynamic one (e.g. a shell
dnl variable).
dnl
dnl Note that this macro removes the newline output by the M4
dnl "esyscmd" built-in. Unless you understand what you're doing,
dnl particularly with M4, do not modify this macro definition.

dnl As of this writing, ACE's ACE_OS::sched_setaffinity() wrapper
dnl facade implementation only supports the latter two varients. So
dnl if the system doesn't define cpu_set_t, we simply avoid checking
dnl for sched_setaffinity(). No attempt is made to verify C library /
dnl kernel consistency.
dnl
dnl The "right" thing to do is to implement something similar to the
dnl PLPA (Portable Linux Processor Affinity) Library, converting the
