This patch silences a couple of more warnings in libjava:
libjava/java/net/natVMURLConnection.cc:64:1: warning: unused parameter ‘bytes’
libjava/java/net/natVMURLConnection.cc:64:1: warning: unused parameter ‘valid’
Tested with a bootstrap on x86_64-linux. Okay for the trunk?

* java/net/natVMURLConnection.cc (guessContentTypeFromBuffer):
Mark `bytes' and `valid' parameters as potentially unused.

There's a #define MAYBE_UNUSED in include/jvm.h, as used in
java/lang/natClass.cc. But maybe jvm.h isn't available here?
cheers,

It is ok to include jvm.h from any of the CNI code.
But, it is also ok to just use an unadorned __attribute__. We know this
code can only be compiled by g++.

... given which, it's hardly worth adding a new header dependency just to
get the macro. Right, thanks for clarifying that.
