I won't speak for Michael, but my rationale is that, based on
discussions over the last few weeks and based on the patch to
gdb.texinfo that I committed on Monday, we currently don't support C++
on DWARF 1.  The testsuite is cluttered with XFAILs that we have no
reason to believe are either correct or comprehensive; the two obvious
choices, then, are to either throw them out entirely or to XFAIL
everything, which are Michael's options 1 and 2.

If at some point in the future somebody decides to start working on
improving C++ DWARF 1 support in GDB (and, presumably, in GCC), then
that person can take the time to sort through what works, what doesn't
work because of failures in GDB, what doesn't work because of failures
in GCC, and what doesn't work because of limitations in the debug
format.  I doubt anybody will be motivated to do so; getting rid of
the current XFAIL's won't hurt such an effort, however.
