 I just downloaded the latest tarball of Clp (1.13.3), not sure which
 version of CoinUtils is included in there. When trying to compile a file
 that includes CoinSort.hpp (indirectly through OsiClpSolverInterface.hpp)
 with GCC4.5.2 or GCC4.2, I get the following errors:

 It's been a while since I haven't used Clp, but I do not recall having
 that type of errors. It used to compile straight away. Is this a known
 bug? Should I consider downgrading to an earlier version in the meantime?

 Thanks.
