Different Warnings when compiling each Elisp with a single Emacs process?

Different Warnings when compiling each Elisp with a single Emacs process?

[Bastien]

Hi,

I'm trying to understand what compilation warnings are shown when
several files are compiled within the same Emacs process and when
the same set of files is compiled with one Emacs process per file.

Let's assume this is with emacs -batch -Q.

My assumption is that compiling a file does not load it.  So I 
don't really understand why there are different warnings.

Thanks for any hint!

But it loads any prerequisites, see byte-compile-file-form-require.

For starters, each (require '...) form acts like eval-and-compile and each macro
expands before that expansion is compiled.  Then there all the other forms that
will explicitly eval also/only during compilation.
