Where to put dll's in a windows environment?

[Egon Andersen <ean ishoejby dk>]

Hi,

I've been porting an application that used GTK from Linux to MSWindows 
on which I use mingw as the C-compiler, and it works acceptable.
But if I want to move the application to another machine without the 
entire MSYS and MINGW setup, where do I put the required dll files (for 
GTK and friends)?
Are there any rules/guide-lines for that on MSWindows? I could imagine 
x:/windows/system, but is that the correct place?
(I admit that I know close to nothing about the MSWindows systems, so it 
might be trivial.)
I have a faint memory that someone posted something about this on this 
list some time ago, but I haven't been able to find it again.

Best regards
