A couple notes on this patch.

First, we don't support compiling libgcj with a different
version of gcj other than the one it comes with.  The reason
for this is that gcj and libgcj are tightly coupled; for instance
gcj and libgcj both have information about the exact format of
java.lang.Class.

Second, I'm not sure this patch is correct.  E.g.,

+      || src_offset - (-count) >= 0 // check for possible integer overflow

Suppose src_offset==10 and count==3.
Then src_offset-(-count) == 7, which is >= 0,
but no integer overflow has occurred.
(This is a perfectly valid situation if the source
array's length is >= 13)

So, I'm closing this and not checking in the patch.
