Greetings, Marco atzeri!

This has been fixed for Vista and Win7 to my knowledge.
At least last time I ran into issue with strange CMD gehavior in this regard
and asked for checks on more recent systems, people reported that it was,
indeed, a nonissue for them.

Only if application trying to be "helpful" and "sanitize" pathname according
to some self-invented standards. Core fopen() does not care.

Yep, that was the idea.

> Cygpath doesn't check if the path exist

Right. But it should at least care for them being what they supposedly are.
I.e. path starting from // or \\ (or \\\\ for the sake of example) is likely a
network path, rather than a mistype.

Your example is okay, it perfectly illustrates the cygwin mount behavior, it's
just not related to the issue. :)
