I already did some testing before [1] and C++11 support isn't generally
available. I redid the tests and the results with the current trunk
(r52100) are:
--std=c++98 --std=c++0x
g++ 4.4 success failure
g++ 4.5 success success
g++ 4.6 success success
clang 2.9 success failure*
g++ 4.7** success success
*) Didn't do much investigation, clang 3.0 should be released rather
soon, so rather look at it with this version.
**) Actually the gcc-snapshot package in Debian of 20111114, but expect
the same results for g++ 4.7 once released

Variadic templates are won't be in MSVC 11 [2].

I haven't tested with g++ 4.3, but can't compile Wesnoth in c++0x mode
with g++ 4.4, which is the current comiler in Debian stable.
Also on the Mac there seems to be no proper C++11 support at the moment.
So I still think we should wait with using C++11 features until support
on all platforms is better.
