Hi Ginn:

This is great.  I can compile the 3.0.9rc1, but I'm having trouble linking:

/usr/ccs/bin/ld -G -h libffi.so.5 -o .libs/libffi.so.5.0.10  
src/.libs/debug.o src/.libs/prep_cif.o src/.libs/types.o 
src/.libs/raw_api.o src/.libs/java_raw_api.o src/.libs/closures.o 
src/x86/.libs/ffi64.o src/x86/.libs/unix64.o src/x86/.libs/ffi.o 
src/x86/.libs/sysv.o  -R/opt/csw/lib -R/usr/lib -R/usr/sfw/lib 
-R/opt/sfw/lib -R/usr/local/lib -R/usr/dt/lib -R/usr/openwin/lib

-L/usr/dt/lib -L/usr/openwin/lib -lc
ld: fatal: symbol `ffi_prep_raw_closure_loc' is multiply-defined:

type=FUNC);
ld: fatal: symbol `ffi_raw_call' is multiply-defined:
   (file src/.libs/raw_api.o type=FUNC; file src/x86/.libs/ffi.o 
type=FUNC);
ld: fatal: File processing errors. No output written to 
.libs/libffi.so.5.0.10
gmake[2]: *** [libffi.la] Error 1

Is there some other trick that I am missing?
