Server-Extension for Linux CoD2 1.2 / 1.3 and CoD4 1.7 Source/Binaries

[Mitch]

I have a few modifications that fixes a few compile errors in libcod2.cpp

After line 28 add:

		extern char **__environ; 
	

Fixes: '__environ' was not declared in this scope

Replace line 931 with:

		int hook_pthread_self(void) 
	

Fixes: invalid conversion from 'int' to 'pthread_t {aka pthread*}'

On line 1019 you have got this:

		if (stream->_fileno <= 4)
printf("_fileno=%d ", stream->_fileno); 
	

Replace with:

		    int _fileno = fileno(stream);
    if (_fileno <= 4)
    printf("_fileno=%d ", _fileno); 
	

Fixes: 'FILE' has no member named '_fileno'.

Now I can compile all the files on freeBSD, but i have got currently problems with linking the files.
