I've attached an updated patch to ticket #4742.

This adds tests to operations_test.cpp that test the error handling for
both returned error code and thrown filesystem_error. Additionally it
tests proper retrieval of the path from the list of env vars for each of
the platforms.

Also, temp_dir_path now also sets the error_code to ENOTDIR upon failure.

These test pass on Windows XP with MSVC8 and Mac OSX10.5.8 with
Xcode3.1.2 using gcc 4.0.1

I'd appreciate it if others could run the tests on other os/compilers as

Thanks, Jeff
