I'm planning to release Poly/ML 5.4 by the end of this month unless there are any show-stoppers. I've had a couple of bug reports from Phil Clayton and fixed those. I've also fixed a few minor bugs so that it will build on the PowerPC and Sparc. Now is the time to check that your software will run in the current version and let me know if there are problems. Don't forget to run make compiler twice to build the current version (SVN 1189).
