Hi Ovanes. Sorry for not getting back to you sooner. I've been at the 
Astoria Seminar all week, and not checking email. I'm glad you've 
managed to get this working.

The version of xpressive in SVN is very different than the version you 
have. Many of the files you've patched don't even exist anymore! I could 
apply to the patch to the old RC_1_34_0 branch and put an updated 
xpressive.zip in the File Vault, but the next version of Boost would not 
reflect your fixes. I think that's OK because the next version of Boost 
will have Fusion-2 and won't need your patch. If that's ok with you, 
then go ahead and send me the patch (as a SVN patch file against the 
RC_1_34_0 branch, if possible), and I'll apply it.

Thanks,
