Hm... that definition is protected with #ifndef WWW_WIN_DLL, and I
define this symbol.

In HTUtils.h there is the following code:

#ifdef HTDEBUG
#ifdef WWW_WIN_DLL
extern int *		WWW_TraceFlag;	 /* In DLLs, we need the indirection */
#define WWWTRACE	(*WWW_TraceFlag) 
#else
extern unsigned int	WWW_TraceFlag;	     /* Global flag for all W3 trace */
#define WWWTRACE	(WWW_TraceFlag)
#endif /* WWW_WIN_DLL */
#else
#define WWWTRACE	0
#endif /* HTDEBUG */

so it will be looking for an int* WWW_TraceFlag, but this global
variable is not defined anywhere.

Is it defined in a file that I chopped out during CVS import? (I'm
stripping away stuff like examples, Win32 build stuff, VMS stuff etc.)

Should I create a file which contains this variable and something it
points to?

Eg. something like this:

static int theWWW_TraceFlag;
int* WWW_TraceFlag = &theWWW_TraceFlag;
