Is this possible to pass #define from makefile?

[KWo]

The problem is - everytime I'm trying to rescue the hostage - right after I press the "use" button - if there is some bot teamnate near me - it steals my hostage. It was too much annoying for me and I've decide to solve it. The code checks only if the hostage is "used" by some another CT bot. Lack of code to check if some human player is "using" such hostage. The only way to solve this is - to hack the private data. The people from AMX X showed me how to do this (thanks to VEN).
The problem is - data stored in private data are placed in some offsets. These offsets are system depanding - win32, linux and amd64 - they use different offsets for data stored in private data. The AMX X code uses some conditions as:
#if defined __linux__
(...)

#if defined __amd64__
(...)
but I didn't find there how do they pass these __linux__ and __amd64__ to compile code correctly for each system.
The question is - is there a way to pass these __linux__ and __amd64__ as some defined from makefile to have one the same code for all systems, but during compilation compile it correctly without necessity adding somewhere in the code:
#define __linux__
or
#define __amd64__

before compilation?

just use the -D parameter for gcc.

In my oponion using offsets for pvPrivateData is not good idea, since they can be broken by newest cs update. So i have no idea how to define it form makefile.

But i see two possible ways to solve problem, intercepting DispatchUse (not sure if it's work with CS hostages). And track the user use button.

About a second method. It can be put in POD's SoundSimulateUpdate () function in this way (and i think it's good idea):

PHP Code:

else if (pPlayer->v.oldbuttons & IN_USE) // pressed used button?
{
    fHearDistance = 1024.0;
    fTimeSound = WorldTime () + 0.5;

    if ((g_iMapType & MAP_CS) && !IsValidBot (pPlayer))
    {
        MakeVectors (pPlayer->v.v_angle);
        Vector vEye = pPlayer->v.origin + pPlayer->v.view_ofs;

        TraceResult tr;
        TraceLine (vEye, vEye + (gpGlobals->v_forward * 200), dont_ignore_monsters,  pPlayer, &tr);

        if (!FNullEnt (tr.pHit) && FClassnameIs (tr.pHit, "hostage_entity"))
            g_HostagesUsedByHumans.push_back (tr.pHit);
   }
} 


Hopes it help, if not i'm sorry for offtop

They are unchanged since CS1.5. I was afraiding the same way You are now, but the specialists from AMX and AMX X explained me that this stuff is safe. Of course - there are in my code some checks if the data contains really this what I'm expecting to get. Here is the table for all private data "OFFSETS" used by AMX and AMX X.

    Also backpack ammo offsets were all obviously 5 steps too high since unknown time...
