Steve,

Bash doesn't do any special variable translation when calling Windows
apps, so JDK gets the CLASSPATH exactly how you define it.  Since the JDK
expects a CLASSPATH in Win32 format with ";" as a separator, that's the
format you have to set CLASSPATH in.  Don't forget to escape the ";" with
"\" in bash, so it doesn't interpret ";" as the command separator.  Since
the JDK accepts both "/" and "\" as directory separators, it doesn't
matter which one you use (but you'll have to escape the "\"s in bash).

You could also define CLASSPATH in POSIX format and use `cygpath -mp` or
`cygpath -wp` to translate it to Windows format.
