Just to make sure I didn't screw up, I rebuilt the package. The 
"configure" script wasn't told anything different so it builds both 
static and shared. So the first line is the shared library build (which 
works, it finds .libs/rsrc.o) but the static build fails.

Before I migrated over to libtool-2.2.x, I used the tag=CC to compile 
resources (without telling libtool at all anything about windres). Now I 
use RC and it breaks (after LT_LANG([Windows Resource])). Just checking 
and the tag=CC doesn't work with libtool 2.2.x (it almost the right 
thing when compiling, but linking later fails with lt-version.c)
/bin/sh ../../libtool   --tag=CC --mode=compile windres  rsrc.rc -o rsrc.lo
libtool: compile:  windres rsrc.rc  -DDLL_EXPORT -DPIC -o .libs/rsrc.o
libtool: compile:  windres rsrc.rc -o rsrc.o >/dev/null 2>&1

Here's the complete output:
