Sorry. "err.h" is a standard header included in the *BSDs and libc (at
least) which implements a number of simple functions for if your program
crashes. The functions are all called err* or warn*.
If you have a libc (or linux installation), info err.h will provide more
info. The source files are at:
src/lib/libc/gen/{err.c,errx.c,warn.c,warnx.c} (if you have put libc into
src/lib)
Unfortunatly I'm away from my normal machine at the moment so can't provide
an exact listing on the file. However as it is possibly more newlib related,
I'll go and look at their mailing list / archives instead.
