64 bit integer support?

I have read that different versions of the Borland compiler support 64-bit integers with __int64, but I have not been able to get it to work on any of them in 4.0 4.5 5.0 or 5.5. In some versions there is a LONGLONG defined as a _double_ (not an int!)
Another posting I read suggested that 5.02 is the earliest version of the compiler to support this ... is it in 5.0 as well? Or do I have to find a 5.02 somewhere? If so, where could I find it?
The code we are compiling is _not_ for windows, it is for an embedded system, so I would prefer to stay away from 5.5 which seems to target windows only. Our current code is actually compiling under 4.0, so if we could get 64-bit integer support for that version it would be best. Otherwise, the lower the version number the better (assumption: fewer porting issues w/ least version # change).
Thanks In Advance

Yes.

Not much to go on. Can you be more specific?
Note that 5.5 is the only version you list which has support for 64-bit ints.

Correct. But only for 32-bit targets, not for 16-bit.
Ok, above you say only 5.5 supports 64-bit ints, then you say "Correct" to 5.02 also supporting them. Which is it?

No.

>Or do I have to find a 5.02 somewhere?

Yes, but ... it won't help if you must create a 16-bit app.
Nope. I never mentioned a 16-bit target environment.

Possibly on Ebay or other sites which sell used software.

>The code we are compiling is _not_ for windows, it is for an embedded system,

16-bit? Then no Borland (or Microsoft) compiler offers such support. It's only
in compilers which create 32-bit targets. You may want to look elsewhere for
large number support libraries (freeware/shareware/commercial.)
It's a 32-bit target processor, but it's _not_ a Window OS. 5.5 seems to compile/link for Windows only while earlier versions don't force the production of Windows target apps. Or am I missing something on 5.5?

Correct. (Win32) Note that 5.5 is from the Builder version 5 package.
64-bit int support was added to BC++ 5.02 for compatibility with Builder
version 1.
So 5.02 is the absolute earliest one I could get that supports 64-bit integers? Ok ... does it have the ability to compile/link non-Windows EXEs, or does it force the inclusion of the Windows headers & libraries?
