Pari svn on MSVC 

Hi
I'm trying to get Pari svn running under MSVC 32bit , we allready have Pari-2.4.2-alpha running under MSVC 32bit with/without MPIR/GMP. 

The file
/src/kernel/none/mp.c
has minor buglet which stops compilation on MSVC
this diff corrects the problem


$ diff -u  ../pari/src/kernel/none/mp.c mp.c

      *ap-- = addll(*ap, *up--);
      for (j=1; j<lu; j++)
        *ap-- = addllx(*ap, *up--);
MSVC doesn't like it when LOCAL_OVERFLOW is empty , as the declarations are not at the beginning of the block.
