Yes, it is (at least on my side, not sure about my dbus co-maintainer).

My make (GNU Make 4.1-9.1 as distributed by Debian) doesn't seem to have
anything built-in for .rc files - at least, strings(1) shows me the rules
I'd expect to be built in (.c, .cc and so on) but doesn't mention .rc.

After invoking LT_LANG([Windows Resource]) in configure.ac, is the
Automake-generated build system meant to support compiling .rc files to
.lo and/or .o? I would expect that it should, but perhaps that expectation
is wrong?
