Apparently it does not:
```
lh_mouse@lhmouse-ideapad ~/Desktop $ expand -t4 test.c
extern int printf(const char *, ...);
extern char _fstat32();
int main(void)
{
printf("%p\n", (void *)_fstat32);
}
lh_mouse@lhmouse-ideapad ~/Desktop $ x86_64-w64-mingw32-gcc test.c -lmsvcr80
lh_mouse@lhmouse-ideapad ~/Desktop $ x86_64-w64-mingw32-gcc test.c -lmsvcrt
/tmp/cc9yIfl5.o:test.c:(.rdata$.refptr._fstat32[.refptr._fstat32]+0x0):
undefined reference to `_fstat32'
collect2: error: ld returned 1 exit status
```
