[GRASS-windows] Compiling grass7 on msys/mingw?

I applied this to the Html.make file and tried again. I got:

$ make
if [ "/usr/local/src/grass_trunk/dist.i686-pc-mingw32/scripts/d.correlate"
!= "" ] ; then GISRC=/usr/local/src/grass_trunk/dist.i686-pc-mingw32/demolocation/.grassrc70
GISBASE=C:/MinGW/msys/local/src/grass_trunk/dist.i686-pc-mingw32
PATH="/usr/local/src/grass_trunk/dist.i686-pc-mingw32/bin:$PATH"
PYTHONPATH="/usr/local/src/grass_trunk/dist.i686-pc-mingw32/etc/python:YTHONPATH"
 ; fi
make: *** Recursive variable `PATH' references itself (eventually).  Stop.

Note the "YTHONPATH".

I then checked the variable PYTHONPATH and found that my Arc
installation over-wrote the PYTHONPATH variable to its own folder. I
changed this back to /usr/local/src/grass_trunk/lib/Python and ran it
again (with the original Html.make) and got:

$ make
if [ "/usr/local/src/grass_trunk/dist.i686-pc-mingw32/scripts/d.correlate"
!= "" ] ; then GISRC=/usr/local/src/grass_trunk/dist.i686-pc-mingw32/demolocation/.grassrc70
GISBASE=C:/MinGW/msys/local/src/grass_trunk/dist.i686-pc-mingw32
PATH="/usr/local/src/grass_trunk/dist.i686-pc-mingw32/bin:$PATH"
PYTHONPATH="/usr/local/src/grass_trunk/dist.i686-pc-mingw32/etc/python:$PYTHONPATH"
PATH="/usr/local/src/grass_trunk/dist.i686-pc-mingw32/bin:/usr/local/src/grass_trunk/dist.i686-pc-mingw32/lib:.:/usr/local/bin:/mingw/bin:/bin:/c/Windows/system32:/c/Windows:/c/Windows/System32/Wbem:/mingw/Python"
LC_ALL=C /usr/local/src/grass_trunk/dist.i686-pc-mingw32/scripts/d.correlate
--html-description < /dev/null | grep -v '</body>\|</html>' >
d.correlate.tmp.html ; fi
Traceback (most recent call last):
  File "C:/MinGW/msys/local/src/grass_trunk/dist.i686-pc-mingw32/scripts/d.correlate",
line 103, in <module>
    options, flags = grass.parser()

    func(fullname, *argrest)
OSError: [Errno 2] No such file or directory

rm d.correlate.tmp.html

Before I continue with this, is this some peculiarity with my
installation or a more general problem with grass7 on mingw/msys?

Thanks for the help,
