interval rounded_arith.hpp compilation issues (clang)

[Frederic Py <fredpy@…>]

It appears that the rounded _artith_* classes fail to compile (at least with my version of clang : Apple clang version 3.0 (tags/Apple/clang-211.10.1) (based on LLVM 3.0svn))

The issue appears for both rounded_arith_std and rounded_arith_opp when they try to call the "to_int" static method of the Rounding mother class (which is a template parameter). Replacing the call of to_int(...) by Rounding::to_int appears to solve the issue. But I did not check if such issue was present at other places.

I have attached a patch file for this header that appears to compile properly.

patch file for boost/numeric/interval/rounded_arith.hpp

It's a bit annoying that 4 months after the bug fix, the patch is not included yet into the official distribution. I also had to manually edit the include file (which will be overwritten by a boost update on my mac). There are 4 lines of code to be changed!

I'm experiencing the same problem when compiling with gcc-4.7.
