[PATCH] long long for printf on MinGW

Hi,

Windows/MinGW printf does support printing of long long types, but it 
does not do using %lld etc.

This patch converts %ll (or %...ll) to %I64 as required by Windows.

GDB printf still won't accept I64 as input, but then this is not 
standard compliant so I don't think it really should.

:ADDPATCH printcmd.c:
