There's no 'i' on line 5795 of w32fns.c on the trunk.  That line says:

  w->left_col = 0;

Perhaps some Cygwin specific preprocessor macro converts left_col into
something that triggers the error?  The file compiles fine for me (as
part of the native w32 build).

Please show a preprocessed source of w32fns.c (replace "-c" by "-E" in
the above command, and add "-o w32fns.ii", then post w32fns.ii).
