* ISTM that there is a real problem printing integer*8 (on x86):
* 
* $ cat x.f
*[modified for test suite]
        integer *8 foo, bar
        data r/4e10/
        foo = 4e10
        bar = r
        if (foo .ne. bar) call abort
        end
* $ g77 x.f && ./a.out
*  1345294336
*  123
* $ f2c x.f && g77 x.c && ./a.out
* x.f:
*    MAIN:
*  40000000000
*  123
* $

* Gdb shows the upper half of the buffer passed to do_lio is zeroed in
* the g77 case.
* 
* I've forgotten how the code generation happens.
