source: code/archive/tutorialFS09/src/network/packet/Packet.h @ 10476

Last change on this file since 10476 was 2756, checked in by rgrieder, 16 years ago

Minimising problems when including windows.h because it defines macros like "min" and "max" if not explicitly specified.
There are two headers we use that include windows.h: OgreWindowEventUtilities.h and enet.h. I had to tweak a little bit there as well.
