Hi all. I tried using the following shim header to satisfy <err.h> in a package I want to build.
https://raw.githubusercontent.com/libressl-portable/portable/master/include/err.h It looked pretty neat since it does everything in the header. It did however not work (I guess the "..." and "##" are to blame?) so now I wonder how/if it is possible with the posix compiler on plan9?
