Description
Describe the issue:
In python 3.12 there seems to be an issue with directory handling that is not present in 3.11. In the very least it does behave differently. It seems to be ignoring some path specifications as well and created files in directories where there were none before, ignoring path specifications. Same numpy version, only difference is Python 3.12 instead of 3.11.6.
Likely related to meson backend, and that I use a runtime parameter combination that may not have been used/tested before/otherwise.
Maybe this can be fixed easily by someone familiar with the meson backend.
(or advise what I am doing wrong - that said, it does work with Python 3.11 and compatibility may be preferable)
Reproduce the code example:
my calls are
f2py3 --verbose -m _interface -h /home/alex/python/source/multistar/_build/_interface.pyf --f2cmap /home/alex/python/source/multistar/.f2py_f2cmap interface.f90 --overwrite-signature
then
```shell
f2py3 --verbose --build-dir /home/alex/python/source/multistar/_build --f90flags="-fPIC -fno-second-underscore -O3 -funroll-loops -fconvert=big-endian -I /home/alex/python/source/multistar/_library" --f77flags="-fPIC -fno-second-underscore -O3 -funroll-loops -fconvert=big-endian -I /home/alex/python/source/multistar/_library" --f2cmap /home/alex/python/source/multistar/.f2py_f2cmap -c -m _interface /home/alex/python/source/multistar/_library/library.a interface.f90 /home/alex/python/source/multistar/_build/_interface.pyf
### Error message:
