* configure.in: Use AC_CANONICAL_HOST, not AC_CANONICAL_TARGET.
	(CLASSPATH_SEPARATOR): New substitution variable.
	* Make-rules (CLASSPATH): New variable.  Make Cygwin-safe.
	(java-classes.stamp): Use -classpath option rather than CLASSPATH.
	(KAWA_COMPILER): Likewise.

	* bin/Makefile.am (kawa.sh): Fix so it works on Cygwin.

	* testsuite/Makefile.am: Various changes to make (most of) the tests 
        work on	Cygwin - make use of CLASSPATH_SEPARATOR; quote path strings
	in case of spaces or semi-colons.
	(DIFF): New variable, so we can run diff with --strip-trailing-cr.
	* HelloCgiS.scm: Minor tweak to match expected output.
