Without looking any deeper at this (sorry), clang doesn't not
accept elseif, it requires elif.
gcc actually doesn't do what you expect with elseif. It just
ignores it if the #if isn't added, and causes a compile-time error
if you end up actually reaching that line. So in:
#if defined(X)
#elseif defined(Y)
#endif
If X is not defined, nothing is included even if Y is defined. If
X is defined, a compile-time error always occurs.
in you want someone with gcc, clang and c++0x experience have a
dig through these headers, I am happy to download them and have a
look.

Sure enough. Good eye! I edited the sets.h and that error is gone.
After reducing the example code to::
suppressMessages( require( inline) )
suppressMessages( require( Rcpp ) )
test <- cxxfunction( sig=signature(),
body='
using namespace Rcpp;
return R_NilValue;
',
plugin="Rcpp",
verbose=FALSE)

The circular reference is still there (clang 3.3)::

This is also fixed in svn (having just checked it out).
You can locally fix it by changing line 36 from:
conversion_to_bool_is_forbidden<x>{
to:
forbidden_conversion<x>{

And using clang 3.0::

I would guess this is caused by clang 3.0's c++11 support not being very
good. I certainly would be tempted not to try to fix it, unless there is
a good reason for it. clang 3.2 should be out very shortly, with very
good support.
