Hm. I'm sorry, I wasn't clear enough. From MSDN on
SHGetFolderPath:
This function is a superset of SHGetSpecialFolderPath,
included with earlier versions of the Shell. On
systems preceeding those including Shell32.dll version
5.0 (Windows Millennium Edition (Windows Me) and
Windows 2000), SHGetFolderPath was obtained through
SHFolder.dll, distributed with Microsoft Internet
Explorer 4.0 and later versions. SHFolder.dll always
calls the current platform's version of this function.
If that fails, it will try to simulate the appropriate
behavior.
So, I think your patch is a good first step, to use
GetProcAddress rather than letting the linker do it.
A next step would be, I think, to do what I suggested:
if this fails, try to GetProcAddress for
SHGetSpecialFolderPath, since this was available on
older versions of shell32. You might have to search
by ordinal if searching by name fails.
So, I don't think my suggestion is that different from
Juergen's, just that I suggest an implementation of
"try to simulate the appropriate behavior" if the
function is not in fact in shell32.

Maybe, but it became of no use.

I don't know ordinal value of this function. The only way to get it for
me would be to debug shfolder.dll DllMain() from/on some old windows
boxes. OTOH, Juergen writes [1]:
* > Which means Win98's shell32 does not have an SHGetFolderPath at

* It has a SHGetFolderPathA exported by ordinal. (like the nt4 one has

* clean way.
So if SHGetSpecialFolderPath* can be found this way, maybe
SHGetFolderPath* could be found also? It is a pity I have no Win95 box at
my hand and cannot test this situation with very old version of
shell32.dll.
So, I don't think my suggestion is that different
from
Juergen's, just that I suggest an implementation of

Yes, I understand now. IMHO, the easiest way still would be to move the
code from shell32 to shfolder. But forget it.

I neither. I don't have this versions handy at the
moment either. Maybe some kind soul who does can
provide them?

I'm not sure that's true. It depends how the
application decides whether to look for these
functions in shfolder.dll. I'm not sure what the
"correct" way is; MS isn't very clear on this. I
think, reading from MSDN, you can ship shfolder.dll
and dynamically load it if you can't find these
exports in shell32.dll. But that apparently isn't
what your app is doing, and I'm not sure what it is
doing instead.
For what it's worth, I'm working on the functions
SHGetFolderPath/A/W, SHGetFolderLocation/A/W,
SHGetSpecialFolderPath/A/W, and
SHGetSpecialFolderLocation/A/W. They're a bit off at
the moment, but not horribly so; I don't think too
many apps will be broken by their incorrectness. But
if your app is having trouble specifically because of
these, help may be on the way :)

My linux box has a dyfunct (partially working) Win95 partition, and I

What are the specific filenames again?
Oh, and do you want them compressed in any way (i.e. leave them, zip
them, or tar/gz them), and do you want them on list or off? Note, that
I'll only do this once, so that means that if you want an archive, I'd
have to send them to the list.
