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


struct __stat64 is guarded by an #ifdef __INSIDE_CYGWIN__.

You must either #define __INSIDE_CYGWIN__ or
winsup/cygwin/include/cygwin/stat.h must change to

#if defined (__INSIDE_CYGWIN__) || defined (_COMPILING_NEWLIB)

I guess the latter is the better approach.


I agree.

If you are willing to make the change on the Cygwin side, let me know and I will change the newlib code.
