If I were using a library, I'd prefer that it didn't have an unnecessary
dependency on another library that would require me to add that other
library to my build system (which, at least under Linux, would be
necessary), or that would require me to hunt down an unofficial library
before I could use it.

I saw it and noted it. I didn't think it needed a response, especially
as there was a suggestion to make XInt a header-only library.

I'm confused... what is the difference between having two separate
libraries and having a compile-time option? The compile-time option
leads directly to having two separate compiled versions of the library.
