The problem is that MSVC doesn't use configure script now. I think
that no compiler except that which we used till moment has problems
with __restrict__. So probably we could just add another define
HAVE_RESTRICT__ which is always set to true in config.h, but MSVC will
not use it.

With this approach above could would turn to:

#ifnded HAVE_RESTRICT__
#define __restrict__
#endif

Also I noted this problem with MSVC8, but maybe that's because of some
option I swithced in a wrong position.
