Now you put it back the way it was before which is wrong. Gmake does not
behave this way. Before your change the following Makefile printed:

--- Makefile ---
all:
        echo makelevel=${MAKELEVEL} make=${MAKE} makeflags=${MAKEFLAGS}
        echo .makelevel=${.MAKELEVEL}
        ${MAKE} l1

l1:
        echo makelevel=${MAKELEVEL} make=${MAKE} makeflags=${MAKEFLAGS}
        echo .makelevel=${.MAKELEVEL}
--- Output gmake ---
    echo makelevel=0 make=gmake makeflags=
    makelevel=0 make=gmake makeflags=
    echo .makelevel=
    .makelevel=
    gmake l1
    gmake[1]: Entering directory `/u/christos'
    echo makelevel=1 make=gmake makeflags=w
    makelevel=1 make=gmake makeflags=w
    echo .makelevel=
    .makelevel=
    gmake[1]: Leaving directory `/u/christos'
--- Output make before your fixes ---
    echo makelevel=0 make=make makeflags= 
    makelevel=0 make=make makeflags=
    echo .makelevel=0
    .makelevel=0
    make l1
    echo makelevel=1 make=make makeflags= 
    makelevel=1 make=make makeflags=
    echo .makelevel=1
    .makelevel=1
--- Output make after your fixes --
    echo makelevel=1 make=/usr/src/usr.bin/make/obj.amd64/make makeflags= 
    makelevel=1 make=/usr/src/usr.bin/make/obj.amd64/make makeflags=
    echo .makelevel=
    .makelevel=
    /usr/src/usr.bin/make/obj.amd64/make l1
    echo makelevel=2 make=/usr/src/usr.bin/make/obj.amd64/make makeflags= 
    makelevel=2 make=/usr/src/usr.bin/make/obj.amd64/make makeflags=
    echo .makelevel=
    .makelevel=

As I mentioned before, it makes no sense to keep the variable internally at
X and pass it to the program at X + 1, and as demonstrated, this is not
what gmake does.
