cygpath returns garbage if DOS/win2k input environment variable is too long?

[Randall R Schulz]

Ralf,

In addition to the need to use "-p" in this case (which I mentioned 
earlier--you did see that message, didn't you?), you should quote your 
$CLASSPATH variable reference.

You might want to scrutinize you scripts to make sure they're 
"space-tolerant." Many Unix-land scripts are written under the assumption 
that there are no characters in variable names and arguments that are 
special to the shell that interprets that script. Under Windows, this is 
often a bad assumption and a space is the most common (but by no means the 
only) character that violates that assumption.

Note that it's not easy for "cygpath" to issue errors when you misuse it, 
since anything you pass in can be converted between Unix and Windows or DOS 
formats. But if you ask it to perform the wrong conversion, you shouldn't 
expect the right result. About the only diagnostic it could provide would 
be for the use of characters that are forbidden in Windows file names (\, 
/, :, *, ?, <, >, |).
