That's not the issue: AFAIU, GDB already builds with clang.

The issue is how much effort would we want to invest for that, and
what are we willing to give up when using GCC to be able to use other
compilers.  For example, the proposed patch adds an explicit "-x c++"
switch to _all_ compilations, and also tweaks the warning switches.
I'm not sure we want GCC builds to be affected so that clang builds
could be cleaner.  But maybe we have a policy about this which deems
these issues acceptable?
