Details:

cl_dll\MOTD.cpp contains older/earlier version of MOTD implementation. This has probably been replaced by vgui_MOTDWindow.cpp.

cl_dll\scoreboard.cpp contains older/earlier version of scoreboard implementation. This has probably been replaced by vgui_ScorePanel.cpp.

cl_dll\soundsystem.cpp appears to contain several functions for loading/unloading modules to be used by older/earlier sound API?

dlls\AI_BaseNPC_Schedule.cpp appears to have the same content as dlls\schedule.cpp, but the only difference is the end date in the header.

dlls\glock.cpp appears to be an older version of the glock, before client side events were introduced.

dlls\hlgl.def enumerates which functions to export from DLL by ordinal. Some of the functions listed do not exist anymore while others are now passed using a function table in GetEntityAPI/GetEntityAPI2.

dlls\mpstubb.cpp contains stub implementations of CGraph and CBaseMonster?

dmc\cl_dll\MOTD.cpp same as cl_dll\MOTD.cpp.

dmc\dlls\dmcgl.def same as dlls\hlgl.def.

dmc\dlls\hlgl.def same as dlls\hlgl.def.
