* lib/die.h (die): New file/function from grep/coreutils. Note: this file will probably be migrated to gnulib. * lib/Makefile.am (libfind_a_SOURCES): Reference it. * xargs/xargs.c: Include die.h. (xargs_do_exec): Use die in place of error-nonzero, thus allowing the compiler to know that we do not fall through into the 0 (child) case.
