I'm not sure; some of the compilers which have trouble with ICEs are
older EDGs, which as you know tend to have surprisingly good
capabilities in some areas.

Note that I suggested supply enable_if_c for your usage.
Neither version forces MPL on people:
template <bool X> struct B { static const bool value = X; };
can be used to adapt:
enable_if< B<whatever>, ... >
