Date: Thu, 16 Jan 2003 13:48:31 +0200 From: "Mike Gorchak" Subject: All QNX patches whole patches concerning QNX. Almost all code has been rewritten by Julian and me. Added initial support for hw overlays in QNX and many many others fixes. P.S. This patches has been reviewed by Dave Rempel from QSSL and included in SDL 1.2.5 distribution, which coming on 3rd party CD for newest 6.2.1 version of QNX, which will be available soon.
