Hi Andrew,

Thanks for the information.

I downloaded and install the tar files for the patched cross-compilers from the links you sent.  I rebuilt base and synApps, and indeed it fixes the problem:

Ok, you are both using a cross-compiler from Dave Thompson, which is missing a 
whole load of patches that are included in Wind River's official compiler.  I 
published a copy of the official Wind River compiler built for Linux a few 
months ago, which generates this output:

tux% /usr/local/vw/tornado22-ppc/host/x86-linux/bin/ccppc -v

Ron, please update the tornado22-ppc/host/x86-linux compiler in APSshare to my 
new one(s).  See the "Binary Downloads" section on the page
    http://www.aps.anl.gov/epics/base/tornado-linux.php
