In newer versions of mingw, programs compiled with FORTIFY_SOURCE need
to link to libssp or they will have link-time errors.

Would an alternative be to just add libssp or am I missing something?

@SuperSandro2000 We'd have to add it to all links with fortify enabled, but just adding -lssp when fortify is given results in failed autoconf checks. Would need to track down the proper fix.

@alexfmpe and I were looking into this (see #132199). I think this is a good temp fix. I hope to fix it more properly with #132343 (which has been a long time coming!).

That's more or less the conclusion I reached in #132188 (comment)

Just for the record: I did not break pkgs.gmp as would be discoverable by nixpkgs-review, as @shlevy seems to feel the need to imply constantly. I assume some cross package he uses broke.

@pstn Apologies for the lack of precision, I did mean gmp cross-compiled to mingw in that commit.

I don't know what you mean by "feel the need to imply constantly." I just put that in one commit message to explain why this was needed now and not before.
