On VC7 it is 1300. Just checked.

Hmm, I highly suspect we really use _MSC_VER (only one leading _). If so, we 
can improve a bit our process.

_MSC_VER is defined by Microsoft C compiler since v.6 (around 1989). Its 
"value" (this is a string, of course) is v00, where v is the number version. So 
version 6 (whatever the target, BTW) was defined as 600; C/C++ 7.0 was 700. 
Straightforward so far. The additional thing to know is that the product have 
been renamed by marketing department, but (hopefully) the compiler version 
number stayed. So Visual C++ 1.x (being 1.0 for Windows ie the 16-bit compiler, 
1.0 for Windows NT ie the 32-bit compiler or 1.5x for Windows) is really 
version 8.0 (hence Steve's version number); and _MSC_VER is 800 for this 
version.

Alike, VC++ 2 have 900, VC++ 4 (marketing did strike again, there is no
VC++3) have 1000, VC++ 5 have 1100 and VC++ 6 have 1200 (and I expect
VC7 to have 1300, but I did not check that).

The additional information is that VC++ 2 does have a __int64 (and __int128) 
type, while VC++ 1.x (any version, include the one for NT) does not. So if we 
are to use _MSC_VER to toggle in the __int64 type, we should restrict ourselves 
to it being defined *and* >= 900.
