<div>Dear Helmut and Markus</div>
<div> </div>
<div>I checked out the Helmut's suggestion, and in fact are there a MinGW-w64</div>
<div>that is a mix between 32-64b. I think it is a very promising solution for</div>
<div>windows-based users, mainly because many of new computers that we buy for GIS end-users area, in general, with large memory (4Gb+) and 64bit.</div>
<div> </div>
<div>But as Helmut advice, I can get in trouble if we mix 32 & 64b. Addictionally, I have no idea of how many users compile grass from source under MSYS/Windows using the easy-to-follow and valuable intructions found at <a href="http://trac.osgeo.org/grass/wiki/CompileOnWindows" target="_blank">http://trac.osgeo.org/grass/wiki/CompileOnWindows</a><br>
</div>
<div>I think rare people will be able to bypass the difficulties of try compile grass under windows using other configurations/libs different from the instructions above. So, if someone feel confortable to try, and could prepare a <u><font color="#0066cc">CompileOnWindowsW64 </font></u>it will be great. </div>
<div> </div>
<div>By the way, the new python-based grass7 will still have the same limitations under windows (not use LFS and only run as 32b)?</div>
