Comment (by knowledgejunkie at gmail.com):

 I've been fighting latest SVN (12834, clean source 'svn export'ed from
 checkout) to compile at all on a slave machine, which I am trying to
 upgrade from a pre-12645 build. What I need to know is the correct
 incantion of flags to get a successful compile on a CeleronD (Prescott?)
 2.4GHz CPU, as I don't seem to be able to get a build even without my
 normal 'enable-proc-opt' flag. This CPU has NetBurst but (only) 256KB
 cache, so I'm not sure if I should configure as a pentium4 when running
 configure.

 Compilation error (as with OP):

 Due to major instability in this slave backend over the past week I took a
 closer look and noticed that all SVN upgrades had failed in the past 2
 weeks, leaving the system stuck at stable 12477. My Athlon64 master
 backend and PentiumM laptop both compiled without any problems yesterday.
 When I delved into things earlier, I worried that my CPU was bad, but then
 saw this ticket and hope it can be resolved.

 Thanks in advance for any advice,
 Nick Morrott
