You likely obtained your cvs source from the development HEAD version.
Hence, your rtems source is what will become release 4.11 some time in the
future.

You need to specify the 4.10 branch when checking out code from the cvs
repo:

cvs -d :pserver:anoncvs at www.rtems.com:/usr1/CVS co -rrtems-4-10-branch rtems

This version will have the correct newlib patch:
newlib-1.18.0-rtems4.10-20100426.diff

Note: you will need to re-build your toolchain with the correct patches from
contrib/crossrpms/patches, and likely need to download the correct base
versions of the tools (i.e. gcc-4.4.4, etc)
