..You're correct that we need memory included to get configure to work.

There are 3 files in all which need to be changed - one for configure to 
succeed and 2 to add '#include <limits>'. This is in the upstream issue 
as well.

I can now configure and compile with gcc 11. testing still TBD.

For convenience I'll put the patch below since it's so short, do hope 
that's ok with folks. My testing is against git master but looks like 
this patch should work fine on the version in arch community as well.


Thanks
