Author: ngie Date: Sun May 22 04:17:00 2016 New Revision: 300395 URL: https://svnweb.freebsd.org/changeset/base/300395 Log: Silence top(1) compiler warnings The contrib/top code is no longer maintained upstream (last pulled 16 years ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type warnings, amongst others. This silences 131 warnings with as little modification as possible by adding necessary return types, definitions, headers, and header guards, and missing header includes. The 5 warnings that remain are due to undeclared ncurses references. I didn't include curses.h and term.h because there are several local functions and macros that conflict with those definitions.
