/* This file contains information about various compilers used to
   build Wget on the Windows platform using its "native" API,
   sometimes referred to as "Win32".  (This excludes Cygwin, which
   defines a Unix-compatible layer and is handled with configure.)

   The above "information about compilers" includes both actual
   differences in compilers (such as how to construct 64-bit constants
   or whether C99 `bool' is available) and the properties of the
   compilation environment and run-time library shipped with the
   compiler (such as whether stat handles large files or whether
   strtoll is present).

   The file is divided into sections for each compiler/environment.
   Being based on free software, MinGW's section comes first and
   contains most of the explanatory comments.  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,
