[boost] [enable_if] compile failure in trunk

trying to merge boost.heap into trunk, there is one issue, which seems to be
triggered by the enable_if in the boost.heap testsuite.

compiling with gcc (4.5 or 4.6), i get the following error:

compiling with gcc against 1.48 works fine. clang++ correctly compiles this
code against boost-trunk. any idea, what could go wrong there?

thanks, tim
