12904	canonical fails for relative symbolic link on NTFS	Matthias@…	Beman Dawes	"I've an path inside a directory which is a symbolic link at an NTFS partition.
The link points to a another directory in the same base directory.

boost throws
{{{
BOOST_ASSERT_MSG(result.is_absolute(), ""canonical() implementation error; please report"");
}}}
in {{{operations.cpp, line 881}}}

Here are more details:
I call {{{boost::filesystem::canonical}} with following ({{{const wchar_t*}}}) parameter:
 {{{L""C:\\Projekte\\50_Workspace\\out\\x64\\.\\audio\\Test.dll""}}}
The current working directory is
  {{{L""C:\\Projekte\\50_Workspace\\out\\x64""}}}
which is a symlink to {{{""x64.Debug""}} in the same base directory (in {{{""C:\\Projekte\\50_Workspace\\out""}}}).

Boost detects that the {{{""x64""}}} is a relative symbolic link and enters the {{{""else""}}} in {{{line 868}}}.
But the created new_source looks strange:
 {{{""x64.Debug/Projekte\\50_Workspace\\out\\x64\\.\\audio\\Test.dll""}}}
In my opinion it should create either
 {{{""C:\\Project\\50_Workspace\\out\\x64.Debug\\.\\audio\\Test.dll""}}}
or
 {{{""C:/Project/50_Workspace/out/x64.Debug/./audio/Test.dll""}}}
for the next loop...
