Hi Rupinder,

   It *is* very basic.  I'm not sure if we want routines that an average
programmer could write in a few lines themselves?  Plus the name

Hmm, you had to create an err.h?  Perhaps we need a ccan module which implements it: it's really useful!

Want to try that?  #if HAVE_ERR_H // #include <err.h> // #else ... kind of thing?

Thanks!
