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.
