There'll be a few for which that's normal, but say when it gets to the
"mpn" directory it should do some building.

Those considered "standard" for gnu packages certainly, plus m4, which
is standard on proper unix-like systems.

That file is supposed to be setup by configure as a symlink to
mpn/x86/gmp-mparam.h, or one in a subdirectory for a particular exact
CPU type. You might need to check "ln" has done its job.

The one on the gmp home page was built for the exact cpu it's running
on, and using gcc, which is normally the key to top speed.
A couple of people have published binaries for ms windows that didn't
use the gmp assembler code, which is pretty much asking for anything
from a 2x to 5x slowdown. Of course one has to get something working
before worrying too much how fast it goes.
