Did you try to use pexports to see if the DLL exports strsignal?

This probably means the configure-time test for strsignal should be
moved to before the test for libgccjit.
But in general, I'd suggest to file a bug report with MSYS2 folks:
the DLL and the import library shouldn't export strsignal.

And that latter function is in libgccjit DLL?
