Of course it's ancient, but from the timestamp (if it was correct)
I'd estimate that it takes 3 to 4 years to get a GNU release to windows :-)

MSYS make 3.81-2 is available (and there is also a MinGW make, a
make using MSVCRT). The MinGW update tool does not
update MSYS make automatically (at least in my installation),
and I rarely compile using mingw32 on windows (cross compilation
from linux works better). So keeping MinGW/MSYS up-to-date
is a little difficult.
