According to “:help getfsize()”

		If the size of {fname} is too big to fit in a Number then -2
		is returned.

and “:help Number” suggests that VimL numbers could be 64-bit

    Number		A 32 or 64 bit signed number.  |expr-number| *Number*

but in reality they aren't

    #if VIM_SIZEOF_INT <= 3		/* use long if int is smaller than 32 bits */
    typedef long	varnumber_T;
    #else
    typedef int	varnumber_T;
    #endif

Always using long for varnumber_T fixes the problem on 64-bit systems
and doesn't break any tests.  However, that won't help on 32-bit
systems and I doubt Bram will accept always using 64-bit.

There's a similar issue with the maximum number of lines that Vim can
handle in a file (c.f., https://bugs.launchpad.net/bugs/1374898) but the
naïve fix doesn't work very well.

Cheers,
