OK, I've put together a scheme which moves the new version macros

as we support in the SWVersion class. Here are the defines.
Please add your comments and ask question, but I hope these will be
self-explanitory. My only concert about SWORD_VERSION_NUM is the
possible size we might get to if we ever get to 5.0. Don't know
how compilers handle macro checking on values over 4GB.
#define SWORD_VERSION_NUM 106902000
In C++03 preprocessing (translation phase 4) happens before things are
converted into C++ tokens (phase 7). Hence this should cause no
trouble during preprocessing. After that, if the literal without a
suffix fits into an int, it is an int. If it fits into (long int) it
is a long int. Otherwise the behavior is undefined. In case its type
would be a 32-bit signed integer type, our maximum version would be
21.47.483.647.
I know this is a microsoft site, but I'm not sure we're safe from their
comment: "The /constant-expression/ is an integer constant
expression..." But then in the same section mentions 'long'.
