Good news, got to look at this on train commute home. It is plainly my
error. And a fix (of just adding #define R_NO_REMAP before #include'ing
Rinternals.h) will be forthcoming. The "length" gave it away.
You can also simply not #include<iomanip> and the error is also avoided.
I'll commit a fix in a bit.
