Thanks a lot, wp!
I nearly came to the same.
Lazarus also asks path to make.exe file, which doesn't come with snapshot.
I tried to use a one from FPC3.0.4, but this doesn't work:
Panic: make: Entering directory `C:/lazarus'
Panic: make: Leaving directory `C:/lazarus'
Panic: Makefile:29: *** You need the GNU utils package to use this Makefile. Stop.
