Peter, Andrew,

The failure on drongo is due to my writing this patch to support meson
versions >= 1.1.0. I setup my local environment to match CI and was
using meson 1.10.0. Before 1.1.0 you needed to pass the include
directory to check_headers with arg:. I have made the changes and
tested python 3.11 w/meson 0.57.2 and 1.0.1. I have also retested with
python 3.14 and meson 1.10.0. Everything passed.

Additional items to note:

1. meson 1.0.1 expects distutils which was retired in python 3.12. If
you want to use a later python with that version of meson (or earlier)
you will need to install setuptools which has a distutils shim I am led
to believe.
2. when building with meson 0.57.2 I had to provide -Dreadline=disabled
for the build to succeed.

The v2 patch is attached.
