It's done... though for some reason buggy (thus again a patch) and currently I am too blind to see the issue. But first things first. I added two new CMake flags, as discussed with Benoit
a) EIGEN_TEST_RVALUE_REF_SUPPORT (enable rvalue references only in the unit tests, not supported on MSVC)
b) EIGEN_TEST_C++0x (enable C++0x features in general, again unit tests only due to missing config file)
Regarding a), I am not sure whether we should look up how to check the actual compiler versions. GCC supports this feature since 4..3 (correct me if I am wrong) and MSVC will starting from version VC10.
Ok, now to the buggy issue I am not able the thrash out. As soon as I activate the ei_ref_to_temporaray struct in TriangularMatrix::swap already the adjoint unit test fails to compile. I have added the code but commented out the part that is causing the issue. I am seriously confused since (assuming EIGEN_TEST_RVALUE_REF_SUPPORT=off), I expected the two lines 309 and 310 to be semantically identical. Maybe somebody has a clue.... uh, btw. I tested with GCC 4.4.1

p.s. What do you think about using CMake in order to create a system/compiler specific configuration file - if somebody want's to use it?
