Where in particular?  I have tried this as well.  Having it defined as empty is of no help.
The compiler needs to know its size and access one of the fields.

With struct __stat64 st;

/home/jjohnstn/sourceware/src/newlib/libc/stdio64/fseeko64.c: In function `_fseeko64_r':
/home/jjohnstn/sourceware/src/newlib/libc/stdio64/fseeko64.c:112: storage size of `st' isn't known
