multiple definition of `MAIN__'

I am still trying to adjust an sgi-fortran-code to linux g77.  I get
this error-message:

main.o(.text+0x10c3): In function `MAIN__':
: undefined reference to `save_vel__'
main.o(.text+0x10d2): In function `MAIN__':
: undefined reference to `save_pres__'
collect2: ld returned 1 exit status
make: *** [calc_les_03_cube] Error 1

Without the two subroutines 'save_vel.f''save_pres.f' the program works

So I tried the 'nm'-utility for the first time and I get this:

         U do_fio
         U do_lio
         U dphidx_
         U dphidy_
         U e_wsfe
         U e_wsle
         U f_clos
         U f_open
         U s_cat
         U s_wsfe
         U s_wsle

00340d10 C flupr_
0035eda0 C geom_
00b722b0 C node_
02709c00 C coef_
061986a0 C vectr_

On I
"In this way the location of MAIN in the code is found and the wrong
routine detected."
So in my example the wrong routine should be placed between vectc allr.
But, how can I find the mistake? What does that mean?
