[Bug java/20654] New: exception.o is not included in libgcj.a due to case-insensitivity

[aaronavay62 at aaronwl dot com]

binutils ar was recently changed to exclude path when comparing object 
filenames, to agree with POSIX.  This combines with Windows' case-insensitive 
filesystem to cause java/lang/Exception.o to replace exception.o in the 
following command while creating libgcj.a.

ar rc .libs/libgcj0_convenience.a prims.o jni.o exception.o ... 
java/lang/Exception.o ...

This causes bootstrap to fail when linking jv-convert.

Since, depending on how you look at it, 'ar' is doing the right thing, I think 
the easiest way to fix this to rename exception.cc to exceptions.cc.

This is why POSIX ar is bad.  Oh well.

This also happens with gnu/java/security/OID.o and org/ietf/jgss/Oid.o, again 
causing build to break in jv-collect.  These files are less easily renamed, 
though.  I don't know how to fix this.

I just checked against "Microsoft (R) Library Manager Version 7.10.3052" and 
binutils's case-insensitivity replacement semantics are consistant with 
Microsoft's implementation.  LIB also has the same path-preserving semantics 
of the previous non-POSIX ar.

I think a better way to fix this would be to check if the P to ar is 
availible, and use it, if it is.

Thanks Danny.  So there is already machinery to fix this; it just needs to be
adapted to be case-insensitive.  I'm working on a patch.
