mplink errors in eclipse

[JohnStewart]

I tried using eclipse ide for code development. But I get a funny error during the mplink step. I tried the same mplink command from a shell and that works fine. Why does eclipse cause this problem?

Here's the build error from eclipse.

My environment is eclipse on Windows XP.
I saw the same problem after installing msys (in order to get the rm command to fix the "clean" problem with eclipse) I uninstalled msys and switched to GnuWin32. Everything is fine now.
