From: "Andy Pfiffer" Subject: [SDL] patch: PocketPC 2000 diffs for release_1_2_6 I was making a backup of my current workspace of SDL for PocketPC, and thought I would send out my diffs. Apologies in advance if the patch has become whitespace mangled. These diffs are relative to CVS tag release_1_2_6, and contain (I think) all changes that have been mentioned on the mailing list in the last few months. I only have PocketPC 2000 & an ARM-based device (iPaq 3635), and I only use Embedded Visual Tools 3.0, so I can't say for sure if it breaks other PocketPC 200[023] builds. --HG-- extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/trunk%40767
