If i uncheck "Generate underscores" in "Project Options" -> "Advanced 
Compiler", i get multiple errors:

[Linker Error] Unresolved external 'memcpy' referenced from 
D:\POLIGON\VPN DEV\VNC_WINSRC\WINVNC\MISSUBSCRIBE\MISDISKINFO.OBJ
[Linker Error] Unresolved external '_lludiv' referenced from 
D:\POLIGON\VPN DEV\VNC_WINSRC\WINVNC\MISSUBSCRIBE\MISDISKINFO.OBJ
[Linker Error] Unresolved external 'sprintf' referenced from

[Linker Error] Unresolved external 'printf' referenced from 
D:\POLIGON\VPN DEV\VNC_WINSRC\WINVNC\MISSUBSCRIBE\MISMACADDRESS.OBJ

Then, if i heck it again, errors disappear...

Weird, what the hell is happening???

Thank you,
Andrey
