This makes ShellMessageBoxW use the correct implementation where the
text buffer size is dynamic, instead of having a too small hardcoded
size.
Fixes CORE-17271.
See also PR #3172 by Kyle Katarn, supplemented with some ideas from
Mark Jansen.
However we cannot straightforwardly implement ShellMessageBoxA around
ShellMessageBoxW, by converting some parameters from ANSI to UNICODE,
because there may be some variadic ANSI strings, associated with '%s'
printf-like formatters inside the format string, that would also need
to be converted; however there is no way for us to find these and perform
the conversion ourselves.
Therefore, we re-implement ShellMessageBoxA by doing a copy-paste ANSI
adaptation of the shlwapi.ShellMessageBoxWrapW function.
Note that, on Vista+ onwards, shlwapi implements both ShellMessageBoxA/W,
and shell32 directly forwards these exports to shlwapi, thus avoiding
these workarounds.
[PSDK] Explicily use WINAPIV for the variadic ShellMessageBoxA/W functions.
[INCLUDE/REACTOS] Add ShellMessageBoxWrapW in shlwapi_undoc.h .

* What is it?
This is a free set of headers and import libraries for the Win32
API. The library differs from the GNU Windows32 library in that I
have tried to use a file structure that mirrors Microsoft's. I
don't like having *all* definitions in one single header as in the
GNU Windows32 library, I want a clean separation between different
parts of the API.
Daniel Guerrero Miralles contributed the DirectX 6.1 import
libraries and DirectX GUID definitions.
See the files NOTES and TODO for what needs to be done.
* Size does matter
Since the WIN32 API is severely bloated (as most MS products seem to
be) the headers are designed to be as compact as possible, while
still being readable, in order to minimize parsing time.
The convention is to omit parameter names for function prototypes,
no excessive white space. Struct/union members are indented with tab
characters to make them readable. Comment only when necessary.
If you are contributing a patch please follow the above mentioned
convention. Make sure your editor does not convert tabs to spaces.
* What do I need to use it?
The library is intended for use with egcs 1.1 or later but it is
possible to use with some other tools as well (although it is not
very useful). LCC-Win32, MSVC and Borland C++ 5.01 or higher may
work as well. The import libraries are for GNU tools only.
The library requires egcs 1.1 or later, since the `#pragma pack'
feature is used. Mumit Khan provides egcs patches and binaries for
win32 at `http://www.xraylith.wisc.edu/~khan/software/gnu-win32/'.
If you are going to use C++ COM objects, you will need a version of
egcs that recognizes the `comobject' attribute and then define
HAVE_COMOBJECT when compiling your program. Antonio Mendes de
Oliveira Neto has a prebuilt version at
`http://li.facens.br/EGCS-WIN32/english/index.html'. Note that this
is very experimental. If you want to use COM objects in C++ but with
C interfaces you must define CINTERFACE.
Objective-C programs cannot use COM functionality because of
conflicts between the interface define and the Objective-C
@interface directive. There is also a conflict between the windows
Obj-C BOOL types. To avoid this conflict you should use WINBOOL in
all places where you would use BOOL in a C/C++ windows program. If
you include any windows headers *after* `windows.h' you must use the
method outlined below:
/* non-windows includes */
#include <objc/objc.h>
...
/* windows specific headers */
#include <windows.h>
#define BOOL WINBOOL
#include <commctrl.h>
...
#undef BOOL
...
/* include other headers */
