Ok. Good point. At first, when I tried the 64bits build, the executable
wouldn't run.
I was afraid that it was because of the addsection tweak. Eventually, it
turned out
that it was the emacs.manifest file that specified the .exe as a 32bits
executable.
Hence the reason for the 64bits manifest. So removing addsection is not a
priority
at all.

Even better point. MSVCRT.dll is provided with the OS and some parts of it
are linked against
this dll. However, Visual Studio provides msvcrt80.dll, msvcrt90.dll,
msvcrt100.dll (one for each
new release of VS) and they need to be redistributed with the program. It
makes sense if you
are building an installer (it is even easy).

So, I have rebuilt emacs with the static libc. It is working too,
except for nt/cmdproxy that required :

This patch is ok for both the static libc and the dynamic one.
Without it, link complains that printf is redefined in the case of the
static libc.
By the way, I don't know how the MingW libraries are organized, but defining
printf and co to spare some functions when linking ... it doesn't work with
cl and
libc/msvcrt because other libc functions are used too : strncpy, strdup etc.
So it is not possible to avoid linking against libc (?).
