[O] makefile for v. 7.9.1 on Windows 7 doesn't work

[Bostjan Vilfan]

Hello,
I notice that the makefile in version 7.9.1 has been changed (with regard to v. 
7.8.11). When I tried to run it under Windows7, it didn't work (the makefile 
for 7.8.11 ran OK). Can anyone provide some information?
Regards,
