You've omitted a piece of information that's very important in the 
diagnosis: the command that produced the error, which is right before 
the error itself.

Without seeing the command, my best guess is that the search path ld 
should be using to resolve that object file isn't being translated to 
the actual Windows directory path -- I vaguely recall that happening to 
me before.

These days, I make a point of building GCC in "identity" mounts, where 
the Unixy path ("/mingw") directly corresponds to the underlying Windows 
path ("C:\mingw"). This shouldn't be strictly necessary, but I suspect 
there are some gotchas that can be avoided that way. To change your 
/mingw to an identity mount, move E:\Temp\mingw\msys\1.0\mingw to 
E:\mingw, and edit your E:\Temp\mingw\msys\1.0\etc\fstab accordingly.

Hope that helps,
