teTeX 2.99.1 can be considered "something of a release candidate". I've made considerable efforts to make teTeX 3.0 [cross] build out of the box for Cygwin, many thanks to Thomas Esser and Olaf Weber.
This release has major changes since 2.0.2, so I do not think it's wise to put this in the test distribution yet. You may give it some testing by pointing setup to http://lilypond.org/cygwin/ or just download it from there. There's a known issue with texconfig that needs the xdvi/XDvi app configuration file, that's duplicated in tetex-bin for now, but texconfig is planned to get a rewrite before 3.0. Please report any non-Cygwin problems with this release to the tetex-pretest list. Enjoy, Jan. -- Jan Nieuwenhuizen <[EMAIL PROTECTED]> | GNU LilyPond - The music typesetter http://www.xs4all.nl/~jantien | http://www.lilypond.org
