[Bug libgcj/22338] New: Mingw: ar case insensitive, libgcj members missing

["klaus dot kusche at inode dot at" <gcc-bugzilla at gcc dot gnu dot org>]

When making libjava on Interix for mingw, compiling jv-convert.exe fails when 
linking with thousands of undefined references.

Closer analysis shows that these are caused by three members missing from 
libgcj.a:
exception.o, gnu/java/security/OID.o and 
gnu/java/net/protocol/http/HTTPURLConnection.o

Trying to add them to libgcj.a by hand with "ar ru" also fails.
The reason is that libgcj.a already contains three members whose names differ 
by case only:
java/lang/Exception.o, org/ietf/jgss/Oid.o and java/net/HttpURLConnection.o

Obviously, on mingw ar handles archive member names case-insensitivly, not 
allowing two members to differ by case only (a natural behaviour on windows).

Could the names be made unique?
