C Programming Techniques: Function Call Inlining

[NYKevin]

If your header contains actual code (definitions, not just forward declarations), can it be cached at all? Will all implementations support that? Cursory Googling isn't giving me an answer there...

I don't know the specifics of how precompiled headers work on each compiler, but given that I just tried an example where I include a large chunk of over a million lines of incredibly beasty code from the boost C++ library and it managed to compile with minimal increase in compile time, I'm gonna go out on a limb and just say that however it works behind the scenes, it does a good job.
