Compile the following test case:
extern "C" {
typedef unsigned long size_t;
int snprintf(char * , size_t, const char * , ...) __asm("_fancy_snprintf");
}
namespace std { using ::snprintf; }
namespace std { void foo() { snprintf(0, 3, ""); } }
If you examine the assembly file or the .o file, you will see that we're
invoking _snprintf. This is wrong.
We should be invoking _fancy_snprintf.
Note that it's important that we're importing into namespace std. If I change
the name to something
else, the problem goes away.
