This reverts commit c313fa4602defe1be947370ab5b217ca163a1e3c.

This is found to cause issues on x86_64 Windows even when using UCRT.

* When there is no sigsetjmp, its functionality is provided by plain

* that MinGW-64 has some longstanding issues in its setjmp support when
* building with MSVCRT, so on that toolchain we cheat and use gcc's builtins.
