In Microsoft mode, force 64 bit hex integer constants to signed type if the LL or i64 suffix is used. This MSVC behavior.
For example:
void f(long long){ printf("long long"); }
void f(unsigned long long) { printf("unsigned long long"); }
int main() {
f(0xffffffffffffffffLL);
}
Will print "long long" using MSVC.
This patch also fixes 16 compile errors related to overloading issues when parsing the MSVC 2008 C++ standard lib.
