	* [msdos/dosmem.c]
	Export address for __0000H, too.

	* [msdos/dpmi.c]

Sat Feb 28 14:04:56 1998  Kristian Nielsen  <kristian.nielsen@risoe.dk>

	* [configure.in] [include/acconfig.h]
	Autoconf macro to check for non-reentrant X libraries.

	* [windows/winpos.c]
	In SetWindowPos32(), do not cause WM_SIZE messages when the
	SWP_NOSIZE flag is specified. This fixes the division-by-zero in
	Borland C++ 4.0 "Open Project" menu item.

	* [windows/win.c]
	Fix winelib class menu loading bug.

	* [include/module.h] [loader/module.c]
	LoadModule32 should be implemented in terms of CreateProcess.

	* [programs/view/*]
	Metafile viewer sample program.

	* [documentation/wine.texinfo] [documentation/Makefile.in]
	Improvements and additions, HTML target.

Fri Feb 27 04:27:48 1998  Dimitrie O. Paun <dimi@cs.toronto.edu>

	* [*/*]
	Switched to the new debug messages interface. For more information
	please refer to documentation/debug-msgs. Because the new scheme
	introduces a new semantic level, I had to manually do through
	about 530 dprintf_xxx!  The rest of about 2400 where transformed
	via a script.  Because of the large number of changes that I had
	to do, some may have not come out as nicely as I wanted them.  If
	this is the case, please let me know. There is a lot of work left
	to do: -- a few hundred printf's to be converted -- about 2300
	fprintf's to be converted -- about 600 FIXME's to be transformed
	The problem is that in the above mentioned cases, a lot of manual
	intervention is required because a lot of the information is
	missing.  There are also a lot of other things to be done to the
	interface and so forth. I have now ideas for a at least a month
	worth of full time work :) I will proceed with many changes in the
	next few releases, so please do not start modifing things because
	there will be a hell of a lot of conflicts. If you have ideas that
	you want to integrate or you want to work on different things,
	please coordinate with me.

Thu Feb 26 13:04:29 1998  David Lee Lambert <lamber45@egr.msu.edu>

	* [ole/ole2nls.c] [include/windows.h]

	* [if1632/builtin.c][loader/module.c][library/winestub.c]
	Small hack so we don't need a dummy BUILTIN_LoadModule
	in winestub.c.

	* [ole/*][relay32/ole32.spec][if1632/storage.spec]
	storage.dll started. winword loads documents (saving

	Added some comments, fixed circular dll references,
	fixed modref ordering, fixed tls allocation.

	* [memory/global.c]
	Added validity checks before every GET_ARENA_PTR.
	(several functions rely on Global* return values
	 on invalid handles, like IsTask).
	Implemented GlobalUnlockFree16.

	* [memory/virtual.c]
	Replaced dprintf_virtual by fprintf, so we can
	do 'info map' again in the debugger. Increase read
	linesize for Linux2.1 cases.

	* [misc/cpu.c][misc/registry.c]
	Moved cpu registry initialization to misc/cpu.c.

	* [multimedia/dsound.c]

	Fixed USER32 ordinal numbers in documentation.

	Added generic k32obj read and write routines for k32objs that
	support I/O.

	* [documentation/console]
	Updated console docs.

	* [win32/console.c]
	Make console work like a k32obj that supports I/O.

	* [include/windows.h]
	Make WriteFile and ReadFile take HANDLE32 for handle.

Sun Feb 15 14:07:07 1998  Dimitrie O. Paun  <dimi@mail.cs.toronto.edu>

	* [controls/menu.c] [misc/ver.c] [multimedia/dsound.c]
	  [multimedia/joystick.c] [windows/dialog.c]
	Modified some dprintf_xxx's to prepare them for a new
	dprintf_ scheme. Basically, I changed the dprintf's that
	outputed a line with many dprintf calls to do just one
	dprintf call.

README.resources

This is a short discussion of resources in WineLib.

Introduction
Resources are used to store dialogs, menus, bitmaps, icons, 
version information, strings, fonts, and accelerators.
In a Win3.1 programming environment, there are three file formats for 
resources:
- the RC script, which is human-readable and can be processed by a resource
compiler
- the .RES file, which is the output of the resource compiler
- the .EXE and .DLL files, which store resources as a part of the NE
file format
For WineLib, only a part of this is supported. In particular, there is no
.RES file, the executable is not a NE file (as it is a native Unix executable),
and some resource types are not implemented: icons, version information,
strings, and fonts.

Building a WineLib application
The build process assumes that the C source files and the resource script
is available. At the moment, a single resource script is recommended.
This script is processed by winerc:
1) the preprocessor is used to resolve symbolic style name (LBS_STANDARD, ...)
into numbers. This involves processing windows.h
2) the unused parts of windows.h (type definitions) are removed. This would
not be necessary if Wine's windows.h would use the RC_INVOKED macro.
3) winerc is invoked to create a binary representation of the resources.
This representation is stored as C source code (arrays).
4) gcc is used to compile the generated C code.
Now, each resource is available as a C array to the application. As the 
executable is not in the NE format, it is not possible to retrieve resource
locations in the executable via name. Instead, the resources have to be
referenced with their generated C array names. The linker then resolves
these names in the compiled resource file.
5) The program sources are compiled and linked with the output of step 4.
A sample build process is in toolkit/Makefile:hello3.

Required changes to the program sources
Because loading the resources from an instance handle is not possible,
the *Indirect functions have to be used to load a resource. The C arrays
can be directly passed to the *Indirect functions. So, instead of writing

	hMenu=LoadMenu(hInstance,"MAIN");

write

	hMenu=LoadMenuIndirect(hello3_MENU_MAIN.bytes);

Fortunately, the Windows API has the following functions available:
DialogBoxIndirect
CreateDialogIndirect
DialogBoxIndirectParam
CreateDialogIndirectParam

LoadMenuIndirect
SetDIBitsToDevice

Sample code is available in hello3.c. hello3res.c contains the corresponding
resources.

Keeping a common source
Clearly, changing the sources is not very desirable, and suggestions how
to reduce the amount of work are welcome. In the meantime, two approaches
allow at least to remain a common source between the Win3.1 code and the
WineLib code:
1) conditional compiles:
When compiling a WineLib application, WINELIB is defined. This can be used
to select Wine-specific code.
2) usage of winerc for Windows: The *Indirect functions are available on
plain Win3.1, and the resource format is fully compatible. Thus, recompiling
sources modified for WineLib on Win3.1 is possible and known to work.

Open problems
1) Icons and cursors: For these resources, there is no *Indirect function
documented. In addition, both are implemented by a set of two resources.
This is the reason why they are not supported by winerc.
2) Accelerators: Although winerc supports accelerators, there is no 
LoadAcceleratorIndirect function. A work-around would be to define one.
3) Fonts: Font resources are not supported by Wine at all.
4) String tables: Although string tables are not supported by winerc, there
is no reason not to add such support. Again, some indirect loading would
be necessary.
5) API requires loading by name: At some places, the name of a resource
is passed instead of a handle. The WNDCLASS structure contains the name
of a menu resource, and the icon in a dialog box is referenced by its name.
(Are there some more places?)
Clearly, loading the resource by name would be highly desirable. The
resource compiler currently creates a structure containing all resources
defined in an RC file. However, it is not clear how WINELIB could find the
location of this structure, especially, when there is more than one RC file.
