I don't have access to a recent enough binutils on Linux that supports
-gdwarf-2, so I can't test myself.  I think someone else will have to
comment on why you're seeing this behavior.

Yes, it is supposed to.  I am not sure what version of binutils is
required for this, but at the very least, it should work on mainline.

Since you initially asked about MinGW, the next MinGW.org binutils
release (or if you build binutils from CVS on MinGW) will support
--gdwarf-2.
