modification of g77 for default 64-bit integers on x86-64

[Jiri Pittner]

g95 is still not mature enough for applications, I am afraid.

My modified g77 works:
|orion:/home/jiri> cat test12.f
      program y
         integer i
         integer*8 j
         print *, bit_size(i)
         print *, bit_size(j)
      end 
|orion:/home/jiri> g77 test12.f;a.out
 32
 64
|orion:/home/jiri> g77_64 test12.f;a.out
 64
 64

The sample program with equivalence compiled with g77_64 without error.
Where the trouble should be?
