What is the main problem?

Looks like a backslash / forward slash problem to me. I guess that you are running this from a cygwin shell, in which backslashes "\" are note recognized, or in your case omitted. Use forward slashes "/" instead and you should be able to have a working "C:/mingw/bin/gcc". HTH, Florent Arnold & Richter Cine Technik GmbH & Co.
