/* This file contains specifics of various compilers supported on the
   Windows platform.  In this case "compiler" can refer either to the
   specific compiler feature (such as how to construct a 64-bit
   constant) or to a feature of the compilation environment shipped
   with the compiler.

   The file is divided into sections for each compiler.  Most of the
   explanatory comments are in the first (MinGW) section to avoid
   repetition.

   Things that apply to *all* compilers, as well as things that are
   specific to Wget, belong in src/mswindows.h.  */

   64-bit fstat!  Because of that we also need a struct_fstat that
   points to struct_stat on Unix and on Windows, except under Borland,
