This works for me with both the MinGW cross and crossed-native builds.
I used automake 1.7.0 and autoconf 2.5.8. Nice job!

I'm still scratching my head about the 10M Makefile.in, and also wondering
about the memory and CPU requirements for generating the build-time
libjava Makefile (about 8M) from Makefile.in at configure time. I haven't
profiled it, but it takes awhile. If it turns out a lot of memory is getting
swallowed in the process, you might get, um, tapped on the shoulder
the same way I did with my compile-all-classfiles patch.

I'm not that well-versed in the autotools. The verbosity in Makefile.in is
stemming from repetition of rules like these for every sourcefile:

----------------------------------------8<---------------------------------------------------------
javax/naming/ldap/libgcj_la-UnsolicitedNotification.o: javax/naming/ldap/UnsolicitedNotification.java
@am__fastdepGCJ_TRUE@	if $(GCJ) $(libgcj_la_GCJFLAGS) $(GCJFLAGS) -MT javax/naming/ldap/libgcj_la-UnsolicitedNotification.o -MD -MP -MF "javax/naming/ldap/$(DEPDIR)/libgcj_la-UnsolicitedNotification.Tpo" \
@am__fastdepGCJ_TRUE@	  -c -o javax/naming/ldap/libgcj_la-UnsolicitedNotification.o `test -f 'javax/naming/ldap/UnsolicitedNotification.java' || echo '$(srcdir)/'`javax/naming/ldap/UnsolicitedNotification.java; \
@am__fastdepGCJ_TRUE@	then mv "javax/naming/ldap/$(DEPDIR)/libgcj_la-UnsolicitedNotification.Tpo" "javax/naming/ldap/$(DEPDIR)/libgcj_la-UnsolicitedNotification.Po"; \

I didn't spend a lot of time on this, but couldn't immediately see who
was responsible for generating the above. Is it automake itself?

In any case, once I applied the patches correctly, everything
worked fine on my end. Thanks again.
