Almost there! If I edit out the call to httrackengine_loop in the
httrackengine_init routine, the build goes through. 
I also had to edit out the call to PlaySound.

Otherwise I get unresolved symbols

WinHTTrack error LNK2019: unresolved external symbol "int __cdecl
httrackengine_loop(struct httrackp *,struct lien_back
*,int,int,int,int,int,struct hts_stat_struct *)"
(?httrackengine_loop@@YAHPAUhttrackp@@PAUlien_back@@HHHHHPAUhts_stat_struct@@@Z)
referenced in function "void __cdecl httrackengine_init(struct
t_hts_callbackarg *)" (?httrackengine_init@@YAXPAUt_hts_callbackarg@@@Z)

WinHTTrack error LNK2019: unresolved external symbol __imp__PlaySoundA@12
referenced in function "void __cdecl httrackengine_uninit(struct
t_hts_callbackarg *)" (?httrackengine_uninit@@YAXPAUt_hts_callbackarg@@@Z)

How do I get around this issue?? I'm using Visual Studio .NET 2003 and the
code is 3.43-2
