g77 used to reject the following program on 32-bit targets:
@smallexample
PROGRAM PROG
DIMENSION A(140 000 000)
END
@end smallexample
with the message:
@smallexample
prog.f: In program `prog':
prog.f:2:
DIMENSION A(140 000 000)
^
Array `a' at (^) is too large to handle
@end smallexample
because 140 000 000 reals is larger than the largest bit-extent that can be
expressed in 32 bits. However, bit-sizes never play a role after offsets
have been converted to byte addresses. Therefore this check has been removed.
Note: On GNU/Linux systems one has to compile programs that occupy more
than 1 Gbyte statically, i.e.@: g77 -static ...
