File (getAbsolutePath): Prefix drive specifier on Windows for paths starting with a '\'.

2003-03-01  Ranjit Mathew  <rmathew@hotmail.com>

	* java/io/File (getAbsolutePath): Prefix drive specifier on
	Windows for paths starting with a '\'.
	(toURL): Make URL more consistent with what Sun's JDK returns.

	* java/io/natFileWin32.cc (java::io::File::isAbsolute): Return
	true only if the path is a UNC network path or it starts with a
	drive specifier.

	* java/net/URLStreamHandler.java (parseURL): Correct minor typo.
	Be prepared to handle either '/' or '\\' in the file path for
	Windows if using the "file" protocol.
	Canonicalise the file path if using a relative path in the given
	context and the "file" protocol.
