Multithread compiler rulez! Persze mindjárt jönnek az előbbi postra RTFM mantrával kontrázó feketeöves coderek, hogyaszonnya:
mpb-efi:~/ihome/prototype/server/src fns$ man make
...
       -j [jobs], --jobs[=jobs]
            Specifies  the  number of jobs (commands) to run simultaneously.  If there is more than
            one -j option, the last one is effective.  If the -j option is given without  an  argu-
            ment, make will not limit the number of jobs that can run simultaneously.
