yes I know the concept, there no benefit on today machine, especially for a .h that is not so huge.
Not to recompile it again?
You know, the concept of precompiled headres...?

I would also keep this feature, however, in the case of SQLite3
amalgamation, I am really confused. You know how we have to #include
the 'stdafx.h' in every declaration file (making it non-portable
code), i.e. .c, .cpp, etc., well, I tried doing the same thing with
sqlite.c, but VS10 complains about it.
You can do that without making it non portable by adding /FI to your
compile line:

Try /FI "stdafx.h"

You might be surprised at the speed increase you see in compile
time if you've got large projects.  The time isn't lost to CPU as
much, but disk I/O time adds up when hitting many hundreds of small
(header) files (even with an SSD).

This is why I use PCH. Building some of my projects take a long time
even on a 12 threaded processor with multiple SSDs.
