Some applications add their paths to PATH quoted, but these paths are
not very common locations to load dlls from.
In the blog referenced earlier I saw this comment: "Turned out the
DirectX SDK inserted its Utilities\Bin\x86 folder at the start of my
PATH and used quotes."

Currently, there are tree variants of ClassLoaderHelper: for Windows,
for Unix and for MacOS.
We have to either duplicate code in Unix and MacOS realizations, or
introduce another Helper class for initializing paths only, which would
have only two realizations: for Windows and all Unixes.
I would choose the second approach.
What would you suggest?
