source: code/branches/pickups2/src/network/packet/ClassID.cc @ 2955

Last change on this file since 2955 was 2773, checked in by rgrieder, 16 years ago

Removed all enet and boost includes from header files in the network library.

  • Reduces dependencies
  • Minimises problems with windows.h
  • Speeds up the compiling process a little bit (probably negligible)
  • Also removes ugly WIN32_LEAN_AND_MEAN declarations before every enet.h include in the network library.

Removed windows.h header from util/Sleep.h by adding Sleep.cc

  • Property svn:eol-style set to native
