Re: *.f *.c linking problem - g77 = gcc (options)?

This is the error messages I got, with the egcs g77 or "gcc -lf2c_broken"
(a stripped out version of f2c without main.o):

------------------------------------------------------------------

/usr/lib/crt1.o: In function `_start':
/usr/lib/crt1.o(.text+0x5a): undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [bin/sim] Error 1

g77  -Wall -o bin/sim  -lm -lnag
