If You want to see my code - send me a pm with Your email address, I can send it You that way. I wanted to upload it at the mirror of the filebase (CFE server), but it looks like Ancient has changed some access rights and nobody can browse my files there. :(

Eventually I decided to compile the project podbot_mm (in MSVC 2010) yourself, pre-inserting my code in order to eliminate all errors at the building.
So KWo
HERE you can take the project (the source code and DLL), and below I present the corrected code:

Changes:
1) add the required headers from HLSDK;
2) added definitions of 'SURF_*' constants;
3) type 'BOOL' is changed to 'qboolean';
4) type 'Math::Vector3D' is changed to HLSDK 'Vector';
5) added check "hostPlayerEdict->pvPrivateData == NULL" in a function 'ShowMagic';
6) in a function 'SetupLightStyles' fixed bug related to 'cl_lightstyle' array.
7) changed the name of the function 'g_engfuncs.ServerPrintf' to 'g_engfuncs.pfnServerPrint'
8) function 'DotProduct' is used instead of the overloaded operator logical OR for calculation of scalar product of vectors.
Excuse me. It all is simply a consequence of the porting of code from my bot, and also because of that that I this code up until that time didn't compile/not checked properly....
