Well, cl.exe for one doesn't do this trick. This means, you'll have to
put it in your build system, and once you've done that, why should you
use the compiler then? Especially, since you'll want to be consistent
across platforms.
You can use LD_PRELOAD (DLL injection on Windows) to pick up the
dependencies. That has the advantage of automatically working for any
compiler or other custom command, for any source language. Tup does this.
Tup was already discussed on this list quite some time ago. Using
LD_PRELOAD to do those things makes my skin crawl. You need to intercept
system calls AND C-library functions and have to hope that the compiler
isn't doing some crazy stuff you haven't considered...
LD_PRELOAD isn't that bad of a hack, actually. Intercepting open(),
read(), and possibly mmap() should cover most cases.
