Ubuntu 22 compilation errors

[rscs]

This keeps coming up as we install on newer boxes.

[2022-06-13 18:03:41] <brandon> hm
[2022-06-13 18:03:51] <brandon> ubuntu 22 problems? some newer library somewhere?
[2022-06-13 18:05:09] <RuneB> yeah, ubuntu 22 moved stuff around
[2022-06-13 18:06:41] <RuneB> ah, commented out #define res_mkquery __res_mkquery and #define dn_expand __dn_expand in include/resolv.h
[2022-06-13 18:07:38] <RuneB> the man page has res_init and res_mkquery under a Deprecated section, so we'll see if it actually still works
