Well... I always though the math libs were linked by default...
(reading tons of man pages)

From "man gcc":
/lib/libc.a standard C library, see
                   intro(3)

From "man 3 intro":

(3M) These functions are contained in the arithmetic library libm.
       They are used by the f77(1) FORTRAN compiler by default, but
       not by the cc(1) C compiler, which needs the option -lm.

So, as I'll say to myself, RTFM ;-)

Thanks!
