Describe the bug
Here's a failed run for example. The salient bit is:

C:\sr\ghc-9.6.1\network-3.1.2.8-47daa736ec70bcbdeddd189bd8a4e60d34db9fe7\lib\libHSnetwork-3.1.2.8-47daa736ec70bcbdeddd189bd8a4e60d34db9fe7.a: unknown symbol `__mingw_vsprintf'

To Reproduce
This needs to be investigated but generally speaking, our validate.sh -s lib-suite on Windows.

Expected behavior
No failure.

System information

• Operating system: Windows
• cabal, ghc: 3.8.1.0 and 9.6.1

Additional context

Sadly enough, we'll have to disable a big chunk of CI on Windows for GHC 9.6.1 if this is not fixed.
