I didn't have it and according to its log, configure was aware of that.
For some reason, it didn't create lib/gmp.h though.  Removing the build
directory entirely and reconfiguring solved the problem.

They don't annoy me much (IIRC compiling with gcc 10 created many more
warnings).  What annoys me most are those spontaneous switches to an
American keyboard layout.  Do you have any idea what could cause them?
I've never seen them before on any system I used to work on.  Is there a
