I want some numbers to differ in every build. How do I do that in c?

Why C? Surely you would do that in your build script.

It doesn't have to be, a basic one would be a few lines.Have all the numbers that need to be unique be randomly generated with any random function and pass in the seed as a compile time parameter.

Call the /dev/random device somewhere in your compilation script.

No, them aren't, it's quite easy actually.
You do
#include </dev/stdin> in your C file and simply append
<<< "int rand_const = $$RANDOM;" to the compiler invocation. That is all, no bloat.

Yes! Pay attention though: double '$' is needed only if you invoke the compiler from a Makefile, if you are compiling from the commandline/script, it's just '$RANDOM'.

Of course in C, you would just put the numbers in a header file, and have that header file be generated at build time.
