Warn about non-string non-integer ARG to #'gensym, bytecomp.el.
lisp/ChangeLog addition:
2013-08-21 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el:
* bytecomp.el (gensym):
* bytecomp.el (byte-compile-gensym): New.
Warn that gensym called in a for-effect context is unlikely to be
useful.
Warn about non-string non-integer ARGs, this is incorrect.
Am not changing the function to error with same, most code that
makes the mistake is has no problems, which is why it has survived
so long.
* window-xemacs.el (save-window-excursion/mapping):
* window.el (save-window-excursion):
Call #'gensym with a string, not a symbol.

| 28 This file exists only because VC++ lacks pragmas that let you change the | |
| 29 default calling convention in the middle of a file. With optimization, | |
| 30 we compile XEmacs using fastcall as the default convention; but | |
| 31 libraries are not compiled this way, and thus need __cdecl in their | |
| 32 declaration. Without the pragma, we either | |
| 33 | |
| 34 (a) depend on libraries that declare their external functions with | |
| 35 suitable preprocessor definitions that we can change; | |
| 36 | |
| 37 (b) force the user to recompile the library with fastcall (not | |
| 38 reasonable); | |
| 39 | |
| 40 (c) hack the headers manually (not reasonable); | |
| 41 | |
| 42 (d) put all calls to the library in a separate file where the default | |
| 43 calling convention is __cdecl (hence, this file). | |
| 44 | |
| 45 In fact, some libraries do make (a) feasible. This is the case with PNG | |
| 46 and ZLIB. JPEG almost does so, since all externs are wrapped with | |
| 47 EXTERN(); but they fail to wrap their definition of EXTERN with #ifndef | |
| 48 EXTERN, so we can't override it. XPM is similar, wrapping their externs | |
| 49 with FUNC() -- again, not overridable. With PNG, we define PNG_EXPORT; | |
| 50 with ZLIB, we define ZEXPORT and ZEXPORTVA. */ | |
