The problem is still there in SVN Trunk as well...
Okay, so apparently not pilot error. Good to know, thanks. FWIW, the coding error appears to be different in uint_t<N> and int_t<N>, though I have not looked at the source code. In particular, int_t<66> won't compile (int_t<65> will), while uint_t<66> will. So uint_t is accepting some invalid values that int_t is rejecting though, as I said, both accept the invalid value (for my machine) of 65. When int_t<66> is rejected, VC11 says this:

gcc 4.7 says:

Neither message is very helpful. Would it be possible to add use of static_assert, at least in C++11 code? Thanks, Scott
