What would be 'unusual or incorrect' in

$ cat hello.F
      program hello
      implicit none
      write(*,*) 'Hello!'
      end

(1)
$ g77 hello.F -o hello -L/usr/lib/gcc/i686-pc-cygwin/3.4.4 -lg2c
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o):(.text+0xab):
 undefined reference to `_WinMain AT 16'
collect2: ld returned 1 exit status


(2)
$ g77 hello.F -L/usr/lib/gcc/i686-pc-cygwin/3.4.4 -lg2c -o hello

$ ./hello
 Hello!

?

I know this...but then '-o hello' contains symbols that satisfy previous
references ? 
(compare (1) with (2))



Cheers,

   Angelo.
