libdiagnostics name clash

[David Malcolm]

I merged libdiagnostics to GCC trunk on Monday:
  https://gcc.gnu.org/wiki/libdiagnostics

Unfortunately I've since discovered there's at least one libdiagnostics
.so already in Debian:
https://tracker.debian.org/pkg/diagnostics
https://packages.debian.org/search?searchon=contents&keywords=libdiag&mode=filename&suite=unstable&arch=any

so I've been asked to change the name.

I'd prefer to avoid having "gcc" in the name.

Some name ideas:

* libdiag
* libgdiagnostics (where we can be ambiguous about what the "g" stands
for)
* libgdiag (less typing)
* libcomplain
* libcomplaint
* libwhining
* libwhine (but sounds like the Windows compat software)

Any ideas?

Thanks
Dave
