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

Are you probably following old instructions? I guess that because I see that 
you disabled jpeg, while I added the jpeg support some months ago...

The -lxdr message means that the configure is looking for the libxdr.dll 
file... while XDR is currently built as static one.

Yes. Follow the instructions in my building guide 
(http://www.webalice.it/marco.pasetti/grass/BuildFromSource.html#Xdr) and 
build XDR as static.

No. But consider that in these days I'm re-designing the whole building 
environment, in order to build GRASS 6.4 and 7 as a "continuous" task.
Along with that I'll release self-installers of the development builds and 
I'll update the building guide.

Marco
