Hi!

I found a really strange build error. I have some sources on the net. I download them, compile, link, everything is OK. I add an inline function to the main .h, still compiles. I use it in one of the .cpp files, and I get:

ToolsDropPane.obj : error LNK2005: "public: static class Upp::Iml & __cdecl CBPImages::Iml(void)" (?Iml@CBPIm
	ages@@SAAAV0Upp@@XZ) already defined in $blitz.obj

Even after pressing undo to remove all changes, these errors persist. Rebuild, clean + rebuild, nothing helps. I've even done a treedif to see, and the files are absolutely identical to their downloaded state. Only happens with MSC8.

I can't post a test case, but do you have any idea how to fix this?
