Hi Adam, what version of boost are you running? I have tried your code with BOOST_GIL_USE_CONCEPT_CHECK enabled and I get no compiler errors. I use VS2010 Express. My boost is some trunk version that's a couple of weeks old.
Christian, I can confirm it does not compile using GCC 4.4.5 on Linux with Boost 1.42. However, it does compile with Boost from current trunk r67439.
