On Long Island, they have an expression for things like that.  It goes
something like:

        Oh, my, gawd.

I guess you know tdsdump has been ported to Win32, too.

Question to you, Mr. Portability:  Do you know of a compiler out there
without 64-bit integer support?  Even VC++ has it (but it's not "long long",
it's __int64, don't get me started).  Anything without it would be
constrained to a 4 GB file length, which seems pretty unlikely these days,
for anything we care about.  

There are four things we can do when we run out of integer bits: 

1.      Punt.  My favored option for now.
2.      Use long, punt if the incoming value is too big.  
3.      Use float & sprintf, taking care w/rounding.  One day.  
4.      Write "atoll" (cf. atoi) w/gcc, offer it in binary/assembler form to
broken systems.  
5.      Use a 64-bit library.
6.      Write a 64-bit library.  

See, the last two don't come under "we can do".  There ain't no free one
(since gcc doesn't need it) and I don't see writing one as a happening
thing.  Maybe Bill does.  

Options 1 and 2 also mean, "Tell 'em to get gcc".

I'm just believing Bill on that one.
