Yes, this is a known issue. For some reason this was working for me when
I sent the patches, and no longer worked when I tested them again :)
My understanding is that it's a bug/limitation with subdir-objects
support in automake: http://mytestbed.net/issues/1327
The 'subdir' part in 'subdir-objects' is important as referring to
some/dir/file.c relative to the current build directory is fine, but
referring to $(top_srcdir)/spice-common/common/sw_canvas.c does not play
well with subdir-objects and lead to the kind of issue you are
describing.

The way I'm planning to workaround this is to add some small
client_sw_canvas.[ch] wrappers which will just #include the needed
files. This will also make it possible to hide the SW_CANVAS_CACHE
#define in there rather than having it in the CFLAGS for every file that
we build. This has the side-effect that subdir-objects is no longer
needed for spice-gtk (it's not required either for spice-common in git
master).

I haven't checked if these changes go well with the server code. Hope to
send the patches for all of that tomorrow...
