 - Yes, but why does it compile with 5.99.44 userland regardless ?
 
 Somewhere between 5.99.44 and now, the C cross compiler had
 change to the options used to build compilers.  Not sure why
 that would make a difference, but..
 
 In looking at the pkgsrc/sysutils/xenkernel33 build, I find the
 following patch makes it all build.
 
 From reading the comment, the Solaris clause is backwards, but I
 hate to make too radical of a change.
 
 FYI: I was also able to build xenkernel41 with the attached
 patch, and without the modifed include/xen/stdarg.h.

     The Force is what holds everything together.  It has its dark side, 
       and it has its light side.  It's sort of like cosmic duct tape.
