Attached patch fixes a long standing problem with boost.filesystem on Tru64 which has resulted in test failures since quite some time. It seems that readdir_r() on this platform behaves incorrect when errno is not set to 0 previous to calling readdir_r(). This problem now has become critical, as it shows up during regression testing with bb.v2, essentially prohibiting the report creation step of the regression test run. Therefore I would like to ask if this patch can be committed.
