error building latest rtems

[Daron Chabot]

This is an RTEMS problem and should be directed at their mailing list:
rtems-users at rtems.org

You can configure rtems with --disable-posix (this may break things when
trying to build EPICS though...), or apply the proper patch to
newlib-1.18.0. You can find this patch in the latest rtems source:
contrib/crossrpms/patches/newlib-1.18.0-rtems4.10-20100402.diff

<rtems-users at rtems.org>The problem is that you're using an incompatible
patch for newlib-1.18.0. Maybe newlib-1.18.0-rtems4.10-20091218.diff from
http://www.rtems.org/ftp/pub/rtems/SOURCES/4.10/ ??

The latest rtems patch for newlib (not sure of the version) includes changes
to the "sched_param" structure in libc/include/sys/sched.h, which the latest
code in score/posix/src now expects.
