Hi Pal thanks for trying.

I don't like to run or decript scripts, I like to review and apply
patches from contributors, why don't you submit one for this? :)

We might provide the prototype ourselfs but I don't think is a good
idea.  I think is probably better not to define HAVE_STRSIGNAL depending
on libgccjit.
