That depends on the applications that make(1) calls. C compilers and linkers do a good job of returning non-zero return codes when errors are encountered. Perl/awk/shell scripts and other applications may or may not depending on the application developer -- well written ones do. Generally, I use && and have yet to experience any problems. Make world and many ports produce much output and take a long time to build. If one doesn't trust the returning of any error codes by applications (or the make process), one will need to keep ones eyes glued to an XTerm or run the build as a batch job in order to check every line of output to verify that the build actually did build successfully. To me this seems paranoid or even Obsessive Compulsive.
