compiling 0.7.3 on cygwin64

Is it known to work, and any suggestions? Should I just grab the latest instead?

Looking in README,  INSTALL.DOS and INSTALL, I figured I should just
run ./configure in cygwin's bash shell.

Doing so, the only things that pop out as issues are

-----------------
checking for gforth... echo "You need to configure with a gforth in
\$PATH to build this part" && false
....
config.status: WARNING:  'engine/Makefile.in' seems to ignore the
--datarootdir setting
----------------

Following that with make,
