Re: current gnulib regex breaks in gawk

Thanks for the report.  What causes the interface to be marked
as GLIBC_PRIVATE?

I don't have the issue you report on either Ubuntu 18.04 or 20.04,
which are the main systems I develop on.  I will try to look into
this some.

Sorry to disappoint you, but I prefer to keep my project such
that the support infrastructure doesn't overwhelm the actual
project code.
