Regression compared to GDB 9, so we should at the very least discuss what to do
for this one.

For reference, the following page at Microsoft web page, current as of Aug
2020,
says the following:

  - Windows 7 end of mainstream support: Jan 2015
  - Windows 7 end of extended support: Jan 2020

... and ...

  - Windows 8.1 end of mainstream support: Jan 2018
  - Windows 8.1 end of extended support: Jan 2023

For Vista, the following page confirms Vista (extended?) supported was ended:

  Apr 2017

Members of the gnulib community might find it hard to spend energy on this
issue, and this may also affect the GDB community's stance on the minimum
requirement in terms of Windows version to build it.

FWIW this seems to be a runtime failure, not a build failure

FTR: The final bit that's missing for us to be able to close this ticket is
a gnulib update on master, so as to import the 2 patches that we manually
added on the gdb-10-branch.

I think Eli is just waiting for someone who's willing to do it to have
their own need of updating the gnulib version we are using. I personally
currently do not have any plans for an update myself.

There have been 3 gnulib updates since the last comment here,
so I think this problem has been fixed.
