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

Last change on this file since 2955 was 2896, checked in by landauf, 16 years ago

Merged gui branch back to trunk.

I did 2 small changes in IngameManager.cc on line 777 and 888 (yes, really), because const_reverse_iterator strangely doesn't work on MinGW.
