30 This file exists only because VC++ lacks pragmas that let you change the
31 default calling convention in the middle of a file. With optimization,
32 we compile XEmacs using fastcall as the default convention; but
33 libraries are not compiled this way, and thus need __cdecl in their
34 declaration. Without the pragma, we either
35
36 (a) depend on libraries that declare their external functions with
37 suitable preprocessor definitions that we can change;
38
39 (b) force the user to recompile the library with fastcall (not
40 reasonable);
41
42 (c) hack the headers manually (not reasonable);
43
44 (d) put all calls to the library in a separate file where the default
45 calling convention is __cdecl (hence, this file).
46
47 In fact, some libraries do make (a) feasible. This is the case with PNG
48 and ZLIB. JPEG almost does so, since all externs are wrapped with
49 EXTERN(); but they fail to wrap their definition of EXTERN with #ifndef
50 EXTERN, so we can't override it. XPM is similar, wrapping their externs
51 with FUNC() -- again, not overridable. With PNG, we define PNG_EXPORT;
52 with ZLIB, we define ZEXPORT and ZEXPORTVA. */
