gdb patch for 64-bit enum values on 64-bit hosts (ia64-linux)

[James Wilson]

I updated my gdb and gcc source trees, and tried to run the gdb testsuite
with your gdb.base/exprs.{c,exp} patch.  Unfortunately, gdb won't work for
me now.  I don't know what the problem is, and it could take a while to
figure out.  Perhaps gdb is broken, or perhaps gcc is broken, or perhaps I
need a kernel/glibc/whatever upgrade.

I did run your new tests on a 32-bit machine (ia32-linux) and got lots of
failures as I expected.  Does the gdb testsuite have any support for host
specific tests?  We can't expect 64-bit tests to work on 32-bit hosts.
