Hi Daniel,

Please note that there won't be any more releases from the
gdb-17-branch, but we can still push commits if that helps downstream
packagers like you.

For the stable branch, a more minimal fix could be to just include
<unordered_map> in the file.  Does that fix the build failure?

On another topic, does the gdb-18-branch look good to you?
