If the 2nd para is to be kept, please adjust it to read as follows:

There is a mostly superset implementation of cpusets under newlib's
libc/sys/RTEMS/include/sys that has Linux and FreeBSD compatibility
and is built on top of FreeBSD bitsets.  This Cygwin implementation
and the RTEMS one could be combined if desired at some future point.

Thanks,
