Sounds like you want the [make_]absolute() function we have been discussing
in another thread. The order of the arguments is reversed, but other than
that the functionality seems the same.

The output should be:
Note that last one demonstrates a deliberate feature rather than a bug. To
make that clearer, the following has been added to the append docs:
Rationale: It is not considered an error for rhs to include a
system-specific-root because it might relative, and thus valid.
For example, on Windows, the follow must succeed:
path p( "c:", system_specific );
p <<= path( "/foo", system_specific );
assert( p.generic_path() == "c:/foo" );
