I did some research on the matter, and it seems that PATH_MAX is only
defined if there actually is a limit, which apparently is not always
the case. Even if defined, the value is often arbitrary or unsuitably
large. So the #ifndef would have to stay, albeit with another name.
Since MAX_PATH was already used in the WIN32 specific section, I
decided to reuse that to avoid confusion with two different names.
Of course, should PATH_MAX be equally valid on WIN32 even though it's
an extension, that section could be changed to use it too if
available. I can verify if that's the case earliest on Monday, since I
have no Windows machine at home, and submit a clean-up patch after
that. In the meantime, this should work perfectly, even if users with
a >1K long home directory might be disappointed. :)

I'll look into a patch for those soon-ish.
