Building Qt with MinGW - strange dependencies

[gluke]

I'm building Qt 4.3.5 on Windows XP from qt-win-opensource-src-4.3.5.zip.
The compiler is mingw 3.4.5, binutils 2.17.50, mingw32-make 3.81, mingwrt 3.15.1, mingw-utils 0.3, w32api 3.11.
I don't use any special config flags. Just configure.exe, mingw32-make. Everything goes ok. But then every (well, almost every) demo or/and example fails to start saying that it misses MSVCP80.DLL. Why, if I build it with mingw?
And that's not all. If I move the folder with demo sources out from C:\Qt and qmake, mingw32-make in it, evrything becomes just fine. And MSVCP80.DLL is not needed any more.
Any ideas?

Maybe you have pre-compiled demos? Have you tried "make clean"?

The problem is solved. I've had installed VC2005 redistributable before, and then uninstaled it but (I guess) not correctly. Windows reinstall solved the problem.
