/* YUUUUUUUUUUUUUUCK!

   This file exists only because VC++ lacks pragmas that let you change the
   default calling convention in the middle of a file.  With optimization,
   we compile XEmacs using fastcall as the default convention; but
   libraries are not compiled this way, and thus need __cdecl in their
   declaration.  Without the pragma, we either

   (a) depend on libraries that declare their external functions with
   suitable preprocessor definitions that we can change;

   (b) force the user to recompile the library with fastcall (not
   reasonable);

   (c) hack the headers manually (not reasonable);

   (d) put all calls to the library in a separate file where the default
   calling convention is __cdecl (hence, this file).

   In fact, some libraries do make (a) feasible.  This is the case with PNG
   and ZLIB.  JPEG almost does so, since all externs are wrapped with
   EXTERN(); but they fail to wrap their definition of EXTERN with #ifndef
   EXTERN, so we can't override it. XPM is similar, wrapping their externs
   with FUNC() -- again, not overridable.  With PNG, we define PNG_EXPORT;
   with ZLIB, we define ZEXPORT and ZEXPORTVA. */
