We are using IBM's XLC  compiler (version 8.0) on a LInux/PPC system.   I have been able to compile boost 1.33.1 with XLC without any showstopping problems.  (The Boost.Wave library has some minor issues I think)   Attempting to build boost 
1.34.0 with the same version of xlc results in multiple compilation failures.   I'm providing one of the build errors in hopes that I can start getting some pointers as to where to look.   I can dig up more compilation errors if needed.   
<br><br>I did have to patch the vacpp.jam file to override the default location of the xlc compiler.&nbsp;&nbsp; There should be a better way to set the compiler location right? <br><br>Suggestions? <br><br>Thanks, <br>--<br><br>Joe
