Andres was asking about the build time with and without NLS.
There is a note in .cirrus.tasks.yml:
# Keep -Dnls explicitly disabled, as the number of files it creates
causes a
# noticeable slowdown.
I have been testing this a bit. Locally, using MinGW, I was not able to
detect any significant difference. On CI runs, the numbers were to
erratic to get any consistent sense. The CI image for Visual Studio
does not appear to have gettext tools installed, so I couldn't activate
it there, and I don't have Visual Studio set up locally, so I haven't
been able to test that.
