use /usr/bin/time  "your compile command without quotes" for more info
read the man page.

I use "/usr/bin/time make" and for the same program (I posted earlier) I got
these information at the end of make:
288.03user 52.67system 6:37.84elapsed 85%CPU (0avgtext+0avgdata
0maxresident)k
0inputs+0outputs (0major+362698minor)pagefaults 0swaps

Are these numbers in second? I don't think that these numbers are equal to
"-ftime-report"? What is wrong? Am I wrong?
Thanks,

`-ftime-report'
     Makes the compiler print some statistics about the time consumed
     by each pass when it finishes.
