Assuming you are running on Windows, and have not called 
path::default_name_check(...), #1 and #3 should be fine, while #2 and #4 
should throw an exception.

Name checking isn't performed on Windows drive specifiers, and of course 
drive specifiers are tested extensively in the regression tests.

Is it possible that the library thinks you are running on something other 
than Windows? You might stick a #error directive in some of the ostensibly 
POSIX-only code in src/path_posix_windows.cpp to verify you are getting the 
Windows version.

What compiler version and standard library are you using?
