see http://lists.gnu.org/archive/html/info-libredwg/2010-08/msg00000.html
(GRASS is GPLv2+)

I've just ported the above over to GRASS 6 (the above was written
for GRASS 7) but ran into some trouble along the way. I compile with
  -Werror-implicit-function-declaration
and that picked up a missing fn prototype in src/dwg.h,


diff --git a/src/dwg.h b/src/dwg.h
index 24d1e25..5ebaa68 100644
--- a/src/dwg.h
+++ b/src/dwg.h

 long unsigned int
+dwg_get_object_count(Dwg_Data *);

+long unsigned int
 dwg_get_entity_count(Dwg_Data *);
 
 Dwg_Object_Entity **


then it built ok (grass7/trunk version too)

I also noticed that dwg_get_object_object_count() was missing
but I'm not sure if that is supposed to be private or not.
.. maybe other fns too?


to run ./autogen.sh I needed to chmod u+x:

diff --git a/autogen.sh b/autogen.sh
old mode 100644
new mode 100755

(how about a shebang in that?)


and finally, how about getting the library packaging done so we
can get it into the debian (& thus ubuntu) archives.
 'apt-cache search dwg' is pretty empty right now and may be a good
way to lure additional developers into the project... :-)
