I'm confused.

Do you compile the same file multiple times (with different preprocessor
defines), and then link more than one copy of the resulting object file
into the same executable?

Or does each of the resulting object files get linked into separate
executables?

And is there some fixed structure to decide which version(s) of the object
file gets linked into an executable, or is this decided by the developer
during each individual compile?

I believe it is.  You just have to use a different target file name each
time.  I can think of a couple ways to accomplish this, if that is enough
to solve your problem.

You could use the Link directive to build each variation of the file in
a different directory, or you can make copies of the source file using
slightly different names, then build them.

But I probably need a better description of your problem to help you.
