AMD64 x86 Linux; f77 trouble with loader ?

["Murakami Hiroshi" <dm at tmca dot ac dot jp>]

Dear, GCC bugs,

This bug is about f77 for the AMD64 x64 on Linux 
(for example Mandrake Linux for AMD64).

The bug sample source code is compiled with  f77 
with -c option to give a.o file fine.
However, the loader (linker) gives error message 
and the a.out file is not made. 
(It seems the linker thinks the .bss area is no more
than 4GB?)

message from the linker is like:
>: relocation truncated to fit: R_X86_64_32S .bss
>collect2: ld returned 1 exit status

This kind of bug makes the fortran very inconvenient
and kills the 64bit address's advantage.

Since, the fortran77 does not have the dynamic array 
allocation mechanizm, the total array size limitation
of just about 4GB makes the fortran user quite sad.
