I always get lots of "Only in dlls/d3d8: basetexture.o, Only in dlls/d3d8: cubetexture.o etc" type lines - How can I get rid of these (I normally edit them out by hand but I forgot this time) - I looked in the man pages and nothing stood out.
You can always filter them out with help of grep:
diff ... | egrep -v "^Only in"
