[Tinycc-devel] sqlite on windows

It works on Linux: tcc insert_data.c sqlite.c -pthread -ldl, but on win64 I get an undefined intrinsic symbol   __faststorefence(). It can be implemented as an mfence instruction, but I think microsoft implements it with xchgl or similar, as below. Should we add this?

#ifdef _WIN64

void __faststorefence(void) {

    long __fence;

    __asm__ __volatile__( "xchgl %%eax, %0" :"=m"(__fence));

    //__asm__ __volatile__("mfence":::"memory");
