f2py fails to link program on windows using v1.26.0 - works on earlier versions of numpy #26352

Can you try again with numpy 1.26.4? Numpy 1.26.3 had a number of f2py-related fixes. |

Hi Nathan
Yes – certainly. I have updated to 1.26.4 and I get a different set of errors:-
```

Hi C:\Users\keith\temp\fib_test>f2py -c fib1.f90 -m fib1 --backend meson ERROR: Unhandled python OSError. This is probably not a Meson bug, but an issue with your build environment. |
Describe the issue:
I have an old fortran program that I access from python using f2py. I have used this successfully on both linux and windows. I have moved successfully to 1.26 on linux but get a link error (1120 unresolved externals) on windows 11. I replicated the problem using a basic fibonacci fortran program (below)
Reproduce the code example:
