And also you cannot find anyting about .if in the GNU make manual, because
it does not exist. Obviously you cannot use BSD make syntax whith GNU make
and vice versa.

Btw did you look in the info pages of GNU make? They contain much more
documentation then the manpage.

If you insist on using the BSD tutorial on a non BSD platform, there is
a program "pmake", that is available on many platforms, that behaves
like BSD make.
