Not that I am aware of, however, you should report this to
the GDB people:

http://sources.redhat.com/cgi-bin/gnatsweb.pl

As you probably know, this is a problem with the GDB
source code exposed by GCC 4.0.x adhearing more strictly
to languge standards.

Not that I understand the issue enough to fix the
iwmmxt.c file myself. As I'm not sure what is intended,
having never used lvalues on the lhs (left-hand-side) of
an expresssion. But since I lurk on the gcc development
mailing list, I have seen discussion related
to this issue over the last several months.
