Still the same errors. As Dirk pointed out, putting iostream first makes
the errors go away in either case.
You have to define R_NO_REMAP in your code before you include
Rinternals.h, as the "Writing R Extensions" manual states. If not,
Rinternals.h will define the length macro (and others...) which is
defined somewhere within iostream or included from iostream.
I caught this in the 7th line of error output:
$ g++ -I/usr/local/lib/R/include -g -c foo.cc
In file included from /usr/include/c++/3.3/bits/locale_facets.h:528,

from /usr/include/c++/3.3/iostream:45,
from foo.cc:3:
/usr/include/c++/3.3/bits/codecvt.h:110:52: macro "length" passed 4
arguments, but takes just 1
...
It's good to read error messages.
