Finite-element.h needs a patch for cstdint.h

Hello, thanks to a kind (very annoyed user) from the AUR (Arch Linux User Repository), I found that the building was broken. I attach a patch. The solution was simple enough. I hope it works for everyone else

I don’t have accounts with Micro$oft. I don’t need acknowledgement.
