Tom, could you please share your views on this? You seemed to be
saying there that we must link libstdc++ dynamically to support
exceptions thrown by source-highlight, but could you perhaps add more
details about the reasons? Also, do the problems you had in mind
affect GDB that is linked statically with source-highlight, and if
not, could we modify the configure script to allow that with
"-static-libstdc++"?

Joel, should I install the same libctf patches we had in
gdb-9.1-branch in the current master? Or would you like to talk to
the upstream maintainer first?

Any reason not to delete those 2 file names from the list?

Simon, any chance you could look into this, or instruct me how to
investigate?
