After having read HACKING, I have moved the BOOST #include
after the #include of base.hh. Enjoy until you have worked out something solid regarding one-letter macros vs. C++ template parameters. With this patch, "make check" passes.

Encountered the same problem with a fresh mtn clone today (revision 22f47ba88188cc15e92de60cc2597df6054809a7).

Workaround was to #include <boost/random.hpp> before the local headers in test/unit/tests/xdelta.cc. A clean approach should avoid the definition of such a macro (in src/sanity.hh) however.

The xdelta unit test fails to build due a symbol conflict with boost >= 1.47

The problem a conflict of L() macro defined by monotone in sanity.hh and L as a template parameter in boost. I was told that single upper case letters are usually used for classes passed as template parameters in C++ code.
