Anyway, that wasn't the cause of the problem; the problem seems to be that gcc-2.9x doesn't recognize the defaulted argument but insists on having an argument anyway. Now i have changed my specializations such that these have *no* arguments and now it works on all my compilers (MSVC6, VC7.1ß, gcc-2.95.3, gcc-3.2).
