New Revision: 294127
URL: https://svnweb.freebsd.org/changeset/base/294127
Log:
Fix warnings with clang/gcc
- Get rid of unused argc/argv variables in main
- Exit on failure with a return code of 1 instead of -1 with err/errx as a
return code of -1 is implementation dependent
- Bump WARNS to 6
MFC after: 5 days
